NAME

       org.freedesktop.systemd1 - The D-Bus interface of systemd

INTRODUCTION

       systemd(1) and its auxiliary daemons expose a number of APIs over D-Bus. This page only
       describes the various APIs exposed by the system and service manager itself. It does not
       cover the auxiliary daemons.

       The service manager exposes a number of objects on the bus: one Manager object as a
       central entry point for clients along with individual objects for each unit and for each
       queued job. The unit objects implement a generic Unit interface as well as a type-specific
       interface. For example, service units implement both org.freedesktop.systemd1.Unit and
       org.freedesktop.system1.Service. The manager object can list unit and job objects or
       directly convert a unit name or job identifier to a bus path of the corresponding D-Bus
       object.

       Properties exposing time values are usually encoded in microseconds (µs) on the bus, even
       if their corresponding settings in the unit files are in seconds.

       PID 1 uses polkit[1] to allow access to privileged operations for unprivileged processes.
       Some operations (such as shutdown/reboot/suspend) are also available through the D-Bus API
       of logind, see org.freedesktop.login1(5).

THE MANAGER OBJECT

       The main entry point object is available on the fixed /org/freedesktop/systemd1 object
       path:

           node /org/freedesktop/systemd1 {
             interface org.freedesktop.systemd1.Manager {
               methods:

   Methods
       Note that many of the methods exist twice: once on the Manager object and once on the
       respective unit objects. This is to optimize access times so that methods that belong to
       unit objects do not have to be called with a resolved unit path, but can be called with
       only the unit id, too.

       GetUnit() may be used to get the unit object path for a unit name. It takes the unit name
       and returns the object path. If a unit has not been loaded yet by this name this method
       will fail.

       GetUnitByPID() may be used to get the unit object path of the unit a process ID belongs
       to. It takes a UNIX PID and returns the object path. The PID must refer to an existing
       system process.  GetUnitByPIDFD() may be used to query with a Linux PIDFD (see:
       pidfd_open(2)) instead of a PID, which is safer as UNIX PIDs can be recycled. The latter
       method returns the unit id and the invocation id together with the unit object path.

       LoadUnit() is similar to GetUnit() but will load the unit from disk if possible.

       StartUnit() enqueues a start job and possibly depending jobs. It takes the unit to
       activate and a mode string as arguments. The mode needs to be one of "replace", "fail",
       "isolate", "ignore-dependencies", or "ignore-requirements". If "replace", the method will
       start the unit and its dependencies, possibly replacing already queued jobs that conflict
       with it. If "fail", the method will start the unit and its dependencies, but will fail if
       this would change an already queued job. If "isolate", the method will start the unit in
       question and terminate all units that aren't dependencies of it. If "ignore-dependencies",
       it will start a unit but ignore all its dependencies. If "ignore-requirements", it will
       start a unit but only ignore the requirement dependencies. It is not recommended to make
       use of the latter two options. On completion, this method returns the newly created job
       object.

       StartUnitReplace() is similar to StartUnit() but replaces a job that is queued for one
       unit by a job for another unit.

       StartUnitWithFlags() is similar to StartUnit() but allows the caller to pass an extra
       flags parameter, which does not support any flags for now, and is reserved for future
       extensions.

       StopUnit() is similar to StartUnit() but stops the specified unit rather than starting it.
       Note that the "isolate" mode is invalid for this method.

       ReloadUnit(), RestartUnit(), TryRestartUnit(), ReloadOrRestartUnit(), or
       ReloadOrTryRestartUnit() may be used to restart and/or reload a unit. These methods take
       similar arguments as StartUnit(). Reloading is done only if the unit is already running
       and fails otherwise. If a service is restarted that isn't running, it will be started
       unless the "Try" flavor is used in which case a service that isn't running is not affected
       by the restart. The "ReloadOrRestart" flavors attempt a reload if the unit supports it and
       use a restart otherwise.

       EnqueueMarkedJobs() creates reload/restart jobs for units which have been appropriately
       marked, see Markers property above. This is equivalent to calling TryRestartUnit() or
       ReloadOrTryRestartUnit() for the marked units.

       BindMountUnit() can be used to bind mount new files or directories into a running service
       mount namespace.

       MountImageUnit() can be used to mount new images into a running service mount namespace.

       KillUnit() may be used to kill (i.e. send a signal to) all processes of a unit. It takes
       the unit name, an enum who and a UNIX signal number to send. The who enum is one of
       "main", "control" or "all". If "main", only the main process of the unit is killed. If
       "control", only the control process of the unit is killed. If "all", all processes are
       killed. A "control" process is for example a process that is configured via ExecStop= and
       is spawned in parallel to the main daemon process in order to shut it down.

       GetJob() returns the job object path for a specific job, identified by its id.

       CancelJob() cancels a specific job identified by its numeric ID. This operation is also
       available in the Cancel() method of Job objects (see below) and exists primarily to reduce
       the necessary round trips to execute this operation. Note that this will not have any
       effect on jobs whose execution has already begun.

       ClearJobs() flushes the job queue, removing all jobs that are still queued. Note that this
       does not have any effect on jobs whose execution has already begun. It only flushes jobs
       that are queued and have not yet begun execution.

       ResetFailedUnit() resets the "failed" state of a specific unit.

       ResetFailed() resets the "failed" state of all units.

       ListUnits() returns an array of all currently loaded units. Note that units may be known
       by multiple names at the same name, and hence there might be more unit names loaded than
       actual units behind them. The array consists of structures with the following elements:

       •   The primary unit name as string

       •   The human readable description string

       •   The load state (i.e. whether the unit file has been loaded successfully)

       •   The active state (i.e. whether the unit is currently started or not)

       •   The sub state (a more fine-grained version of the active state that is specific to the
           unit type, which the active state is not)

       •   A unit that is being followed in its state by this unit, if there is any, otherwise
           the empty string.

       •   The unit object path

       •   If there is a job queued for the job unit, the numeric job id, 0 otherwise

       •   The job type as string

       •   The job object path

       ListJobs() returns an array with all currently queued jobs. Returns an array consisting of
       structures with the following elements:

       •   The numeric job id

       •   The primary unit name for this job

       •   The job type as string

       •   The job state as string

       •   The job object path

       •   The unit object path

       Subscribe() enables most bus signals to be sent out. Clients which are interested in
       signals need to call this method. Signals are only sent out if at least one client invoked
       this method.  Unsubscribe() reverts the signal subscription that Subscribe() implements.
       It is not necessary to invoke Unsubscribe() as clients are tracked. Signals are no longer
       sent out as soon as all clients which previously asked for Subscribe() either closed their
       connection to the bus or invoked Unsubscribe().

       Dump() returns a text dump of the internal service manager state. This is a privileged,
       low-level debugging interface only. The returned string is supposed to be readable
       exclusively by developers, and not programmatically. There's no interface stability on the
       returned string guaranteed, and new fields may be added any time, and old fields removed.
       The general structure may be rearranged drastically between releases. This is exposed by
       systemd-analyze(1)'s dump command. Similarly, DumpUnitsMatchingPatterns() returns the
       internal state of units whose names match the glob expressions specified in the patterns
       argument. The DumpByFileDescriptor()/DumpUnitsMatchingPatternsByFileDescriptor() methods
       are identical to Dump()/DumpUnitsMatchingPatterns(), but return data serialized into a
       file descriptor (the client should read the text data from it until hitting EOF). Given
       the size limits on D-Bus messages and the possibly large size of the returned strings,
       DumpByFileDescriptor()/DumpUnitsMatchingPatternsByFileDescriptor() are usually the
       preferred interface, since it ensures the data can be passed reliably from the service
       manager to the client. Note though that they cannot work when communicating with the
       service manager remotely, as file descriptors are strictly local to a system. All the
       Dump*() methods are rate limited for unprivileged users.

       Reload() may be invoked to reload all unit files.

       Reexecute() may be invoked to reexecute the main manager process. It will serialize its
       state, reexecute, and deserizalize the state again. This is useful for upgrades and is a
       more comprehensive version of Reload().

       Exit() may be invoked to ask the manager to exit. This is not available for the system
       manager and is useful only for user session managers.

       Reboot(), PowerOff(), Halt(), or KExec() may be used to ask for immediate reboot, powering
       down, halt or kexec based reboot of the system. Note that this does not shut down any
       services and immediately transitions into the reboot process. These functions are normally
       only called as the last step of shutdown and should not be called directly. To shut down
       the machine, it is generally a better idea to invoke Reboot() or PowerOff() on the
       systemd-logind manager object; see org.freedesktop.login1(5) for more information.

       SwitchRoot() may be used to transition to a new root directory. This is intended to be
       used in the initrd, and also to transition from the host system into a shutdown initrd.
       The method takes two arguments: the new root directory (which needs to be specified) and
       an init binary path (which may be left empty, in which case it is automatically searched
       for). The state of the system manager will be serialized before the transition. After the
       transition, the manager binary on the main system is invoked and replaces the old PID 1.
       All state will then be deserialized.

       SetEnvironment() may be used to alter the environment block that is passed to all spawned
       processes. It takes a string array of environment variable assignments. Any previously set
       environment variables will be overridden.

       UnsetEnvironment() may be used to unset environment variables. It takes a string array of
       environment variable names. All variables specified will be unset (if they have been set
       previously) and no longer be passed to all spawned processes. This method has no effect
       for variables that were previously not set, but will not fail in that case.

       UnsetAndSetEnvironment() is a combination of UnsetEnvironment() and SetEnvironment(). It
       takes two lists. The first list contains variables to unset, the second one contains
       assignments to set. If a variable is listed in both, the variable is set after this method
       returns, i.e. the set list overrides the unset list.

       ListUnitFiles() returns an array of unit names and their enablement status. Note that
       ListUnit() returns a list of units currently loaded into memory, while ListUnitFiles()
       returns a list of unit files that were found on disk. Note that while most units are read
       directly from a unit file with the same name, some units are not backed by files and some
       files (templates) cannot directly be loaded as units but need to be instantiated instead.

       GetUnitFileState() returns the current enablement status of a specific unit file.

       EnableUnitFiles() may be used to enable one or more units in the system (by creating
       symlinks to them in /etc/ or /run/). It takes a list of unit files to enable (either just
       file names or full absolute paths if the unit files are residing outside the usual unit
       search paths) and two booleans: the first controls whether the unit shall be enabled for
       runtime only (true, /run/), or persistently (false, /etc/). The second one controls
       whether symlinks pointing to other units shall be replaced if necessary. This method
       returns one boolean and an array of the changes made. The boolean signals whether the unit
       files contained any enablement information (i.e. an [Install] section). The changes array
       consists of structures with three strings: the type of the change (one of "symlink" or
       "unlink"), the file name of the symlink and the destination of the symlink. Note that most
       of the following calls return a changes list in the same format.

       Similarly, DisableUnitFiles() disables one or more units in the system, i.e. removes all
       symlinks to them in /etc/ and /run/.

       The EnableUnitFilesWithFlags() and DisableUnitFilesWithFlags() take in options as flags
       instead of booleans to allow for extendability, defined as follows:

           #define SD_SYSTEMD_UNIT_RUNTIME  (UINT64_C(1) << 0)
           #define SD_SYSTEMD_UNIT_FORCE    (UINT64_C(1) << 1)
           #define SD_SYSTEMD_UNIT_PORTABLE (UINT64_C(1) << 2)

       SD_SYSTEMD_UNIT_RUNTIME will enable or disable the unit for runtime only,
       SD_SYSTEMD_UNIT_FORCE controls whether symlinks pointing to other units shall be replaced
       if necessary.  SD_SYSTEMD_UNIT_PORTABLE will add or remove the symlinks in
       /etc/systemd/system.attached and /run/systemd/system.attached.

       DisableUnitFilesWithFlagsAndInstallInfo() is similar to DisableUnitFilesWithFlags() and
       takes the same arguments, but returns a boolean to indicate whether the unit files contain
       any enablement information, like EnableUnitFiles(). The changes made are still returned in
       an array.

       Similarly, ReenableUnitFiles() applies the changes to one or more units that would result
       from disabling and enabling the unit quickly one after the other in an atomic fashion.
       This is useful to apply updated [Install] information contained in unit files.

       Similarly, LinkUnitFiles() links unit files (that are located outside of the usual unit
       search paths) into the unit search path.

       Similarly, PresetUnitFiles() enables/disables one or more unit files according to the
       preset policy. See systemd.preset(7) for more information.

       Similarly, MaskUnitFiles() masks unit files and UnmaskUnitFiles() unmasks them again.

       SetDefaultTarget() changes the default.target link. See bootup(7) for more information.

       GetDefaultTarget() retrieves the name of the unit to which default.target is aliased.

       SetUnitProperties() may be used to modify certain unit properties at runtime. Not all
       properties may be changed at runtime, but many resource management settings (primarily
       those listed in systemd.resource-control(5)) may. The changes are applied instantly and
       stored on disk for future boots, unless runtime is true, in which case the settings only
       apply until the next reboot.  name is the name of the unit to modify.  properties are the
       settings to set, encoded as an array of property name and value pairs. Note that this is
       not a dictionary! Also note that when setting array properties with this method usually
       results in appending to the pre-configured array. To reset the configured arrays, set the
       property to an empty array first and then append to it.

       StartTransientUnit() may be used to create and start a transient unit which will be
       released as soon as it is not running or referenced anymore or the system is rebooted.
       name is the unit name including its suffix and must be unique.  mode is the same as in
       StartUnit(), properties contains properties of the unit, specified like in
       SetUnitProperties().  aux is currently unused and should be passed as an empty array. See
       the New Control Group Interface[2] for more information how to make use of this
       functionality for resource control purposes.

   Signals
       Note that most signals are sent out only after Subscribe() has been invoked by at least
       one client. Make sure to invoke this method when subscribing to these signals!

       UnitNew() and UnitRemoved() are sent out each time a new unit is loaded or unloaded. Note
       that this has little to do with whether a unit is available on disk or not, and simply
       reflects the units that are currently loaded into memory. The signals take two parameters:
       the primary unit name and the object path.

       JobNew() and JobRemoved() are sent out each time a new job is queued or dequeued. Both
       signals take the numeric job ID, the bus path and the primary unit name for this job as
       arguments.  JobRemoved() also includes a result string which is one of "done", "canceled",
       "timeout", "failed", "dependency", or "skipped".  "done" indicates successful execution of
       a job.  "canceled" indicates that a job has been canceled (via CancelJob() above) before
       it finished execution (this doesn't necessarily mean though that the job operation is
       actually cancelled too, see above).  "timeout" indicates that the job timeout was reached.
       "failed" indicates that the job failed.  "dependency" indicates that a job this job
       depended on failed and the job hence was removed as well.  "skipped" indicates that a job
       was skipped because it didn't apply to the unit's current state.

       StartupFinished() is sent out when startup finishes. It carries six microsecond timespan
       values, each indicating how much boot time has been spent in the firmware (if known), in
       the boot loader (if known), in the kernel initialization phase, in the initrd (if known),
       in userspace and in total. These values may also be calculated from the
       FirmwareTimestampMonotonic, LoaderTimestampMonotonic, InitRDTimestampMonotonic,
       UserspaceTimestampMonotonic, and FinishTimestampMonotonic properties (see below).

       UnitFilesChanged() is sent out each time the list of enabled or masked unit files on disk
       have changed.

       Reloading() is sent out immediately before a daemon reload is done (with the boolean
       parameter set to True) and after a daemon reload is completed (with the boolean parameter
       set to False). This may be used by UIs to optimize UI updates.

   Properties
       Most properties simply reflect the respective options in /etc/systemd/system.conf and the
       kernel command line.

       The others:

       Version encodes the version string of the running systemd instance. Note that the version
       string is purely informational. It should not be parsed and one may not assume the version
       to be formatted in any particular way. We take the liberty to change the versioning scheme
       at any time and it is not part of the public API.

       Features encodes the features that have been enabled and disabled for this build. Enabled
       options are prefixed with "+", disabled options with "-".

       Tainted encodes taint flags as a colon-separated list. When systemd detects it is running
       on a system with a certain problem, it will set an appropriate taint flag. Taints may be
       used to lower the chance of bogus bug reports. The following taints are currently known:

       "split-usr"
           /usr/ was not available when systemd was first invoked. It must either be part of the
           root file system, or it must be mounted before systemd is invoked. See Booting Without
           /usr is Broken[3] for details why this is bad.

       "unmerged-usr"
           /bin, /sbin and /lib* are not symlinks to their counterparts under /usr/. For more
           information on this issue consult The Case for the /usr Merge[4].

       "cgroups-missing"
           Support for cgroups is unavailable.

       "cgroupsv1"
           The system is using the old cgroup hierarchy.

       "local-hwclock"
           The local hardware clock (RTC) is configured to be in local time rather than UTC.

       "support-ended"
           The system is running past the end of support declared by the vendor. See the
           description of SUPPORT_END= in os-release(5).

       "old-kernel"
           The system is running a kernel version that is older than the minimum supported by
           this version of systemd.

       "var-run-bad"
           /run/ does not exist or /var/run is not a symlink to /run/.

       "overflowuid-not-65534", "overflowgid-not-65534"
           The kernel overflow UID or GID have a value other than 65534.

       "short-uid-range", "short-gid-range"
           The UID or GID range assigned to the running systemd instance covers less than
           0...65534.

       FirmwareTimestamp, FirmwareTimestampMonotonic, LoaderTimestamp, LoaderTimestampMonotonic,
       KernelTimestamp, KernelTimestampMonotonic, InitRDTimestamp, InitRDTimestampMonotonic,
       UserspaceTimestamp, UserspaceTimestampMonotonic, FinishTimestamp, and
       FinishTimestampMonotonic encode CLOCK_REALTIME and CLOCK_MONOTONIC microsecond timestamps
       taken when the firmware first began execution, when the boot loader first began execution,
       when the kernel first began execution, when the initrd first began execution, when the
       main systemd instance began execution and finally, when all queued startup jobs finished
       execution. These values are useful for determining boot-time performance. Note that as
       monotonic time begins with the kernel startup, the KernelTimestampMonotonic timestamp will
       always be 0 and FirmwareTimestampMonotonic and LoaderTimestampMonotonic are to be read as
       negative values. Also, not all fields are always available, depending on the used
       firmware, boot loader or initrd implementation. In these cases the respective pairs of
       timestamps are both 0, indicating that no data is available.

       UnitsLoadTimestamp and UnitsLoadTimestampMonotonic encode CLOCK_REALTIME and
       CLOCK_MONOTONIC microseconds timestamps (as described above). The timestamps are taken
       every time when the manager starts loading unit files.

       Similarly, the SecurityStartTimestamp, GeneratorsStartTimestamp and LoadUnitTimestamp (as
       well as their monotonic and stop counterparts) expose performance data for uploading the
       security policies to the kernel (such as the SELinux, IMA, or SMACK policies), for running
       the generator tools and for loading the unit files.

       NNames encodes how many unit names are currently known. This only includes names of units
       that are currently loaded and can be more than the amount of actually loaded units since
       units may have more than one name.

       NJobs encodes how many jobs are currently queued.

       NInstalledJobs encodes how many jobs have ever been queued in total.

       NFailedJobs encodes how many jobs have ever failed in total.

       Progress encodes boot progress as a floating point value between 0.0 and 1.0. This value
       begins at 0.0 at early-boot and ends at 1.0 when boot is finished and is based on the
       number of executed and queued jobs. After startup, this field is always 1.0 indicating a
       finished boot.

       Environment encodes the environment block passed to all executed services. It may be
       altered with bus calls such as SetEnvironment() (see above).

       UnitPath encodes the currently active unit file search path. It is an array of file system
       paths encoded as strings.

       Virtualization contains a short ID string describing the virtualization technology the
       system runs in. On bare-metal hardware this is the empty string. Otherwise, it contains an
       identifier such as "kvm", "vmware" and so on. For a full list of IDs see systemd-detect-
       virt(1). Note that only the "innermost" virtualization technology is exported here. This
       detects both full-machine virtualizations (VMs) and shared-kernel virtualization
       (containers).

       Architecture contains a short ID string describing the architecture the systemd instance
       is running on. This follows the same vocabulary as ConditionArchitectures=.

       ControlGroup contains the root control group path of this system manager. Note that the
       root path is encoded as the empty string here (not as "/"!), so that it can be appended to
       /sys/fs/cgroup/systemd easily. This value will be set to the empty string for the host
       instance and some other string for container instances.

       AccessSELinuxContext contains the SELinux context that is used to control access to the
       unit. It's read from the unit file when it is loaded and cached until the service manager
       is reloaded. This property contains an empty string if SELinux is not used or if no label
       could be read (for example because the unit is not backed by a file on disk).

   Security
       Read access is generally granted to all clients. Additionally, for unprivileged clients,
       some operations are allowed through the polkit privilege system. Operations which modify
       unit state (StartUnit(), StopUnit(), KillUnit(), RestartUnit() and similar, SetProperty())
       require org.freedesktop.systemd1.manage-units. Operations which modify unit file
       enablement state (EnableUnitFiles(), DisableUnitFiles(), EnableUnitFilesWithFlags(),
       DisableUnitFilesWithFlags(), ReenableUnitFiles(), LinkUnitFiles(), PresetUnitFiles,
       MaskUnitFiles, and similar) require org.freedesktop.systemd1.manage-unit-files. Operations
       which modify the exported environment (SetEnvironment(), UnsetEnvironment(),
       UnsetAndSetEnvironment()) require org.freedesktop.systemd1.set-environment.  Reload() and
       Reexecute() require org.freedesktop.systemd1.reload-daemon. Operations which dump internal
       state require org.freedesktop.systemd1.bypass-dump-ratelimit to avoid rate limits.

   Methods
       Start(), Stop(), Reload(), Restart(), TryRestart(), ReloadOrRestart(),
       ReloadOrTryRestart(), Kill(), ResetFailed(), and SetProperties() implement the same
       operation as the respective methods on the Manager object (see above). However, these
       methods operate on the unit object and hence do not take a unit name parameter. Invoking
       the methods directly on the Manager object has the advantage of not requiring a GetUnit()
       call to get the unit object for a specific unit name. Calling the methods on the Manager
       object is hence a round trip optimization.

   Properties
       Id contains the primary name of the unit.

       Names contains all names of the unit, including the primary name that is also exposed in
       Id.

       Following either contains the empty string or contains the name of another unit that this
       unit follows in state. This is used for some device units which reflect the unit state
       machine of another unit, and which other unit this is might possibly change.

       Requires, RequiresOverridable, Requisite, RequisiteOverridable, Wants, BindsTo,
       RequiredBy, RequiredByOverridable, WantedBy, BoundBy, Conflicts, ConflictedBy, Before,
       After, OnFailure, Triggers, TriggeredBy, PropagatesReloadTo, and RequiresMountsFor contain
       arrays which encode the dependencies and their inverse dependencies (where this applies)
       as configured in the unit file or determined automatically.

       Description contains the human readable description string for the unit.

       SourcePath contains the path to a configuration file this unit is automatically generated
       from in case it is not a native unit (in which case it contains the empty string). For
       example, all mount units generated from /etc/fstab have this field set to /etc/fstab.

       Documentation contains a string array with URLs of documentation for this unit.

       LoadState contains a state value that reflects whether the configuration file of this unit
       has been loaded. The following states are currently defined: "loaded", "error", and
       "masked".  "loaded" indicates that the configuration was successfully loaded.  "error"
       indicates that the configuration failed to load. The LoadError field (see below) contains
       information about the cause of this failure.  "masked" indicates that the unit is
       currently masked out (i.e. symlinked to /dev/null or empty). Note that the LoadState is
       fully orthogonal to the ActiveState (see below) as units without valid loaded
       configuration might be active (because configuration might have been reloaded at a time
       where a unit was already active).

       ActiveState contains a state value that reflects whether the unit is currently active or
       not. The following states are currently defined: "active", "reloading", "inactive",
       "failed", "activating", and "deactivating".  "active" indicates that unit is active
       (obviously...).  "reloading" indicates that the unit is active and currently reloading its
       configuration.  "inactive" indicates that it is inactive and the previous run was
       successful or no previous run has taken place yet.  "failed" indicates that it is inactive
       and the previous run was not successful (more information about the reason for this is
       available on the unit type specific interfaces, for example for services in the Result
       property, see below).  "activating" indicates that the unit has previously been inactive
       but is currently in the process of entering an active state. Conversely "deactivating"
       indicates that the unit is currently in the process of deactivation.

       SubState encodes states of the same state machine that ActiveState covers, but knows more
       fine-grained states that are unit-type-specific. Where ActiveState only covers six
       high-level states, SubState covers possibly many more low-level unit-type-specific states
       that are mapped to the six high-level states. Note that multiple low-level states might
       map to the same high-level state, but not vice versa. Not all high-level states have
       low-level counterparts on all unit types. At this point the low-level states are not
       documented here, and are more likely to be extended later on than the common high-level
       states explained above.

       FragmentPath contains the unit file path this unit was read from, if there is one (if not,
       it contains the empty string).

       UnitFileState encodes the install state of the unit file of FragmentPath. It currently
       knows the following states: "enabled", "enabled-runtime", "linked", "linked-runtime",
       "masked", "masked-runtime", "static", "disabled", and "invalid".  "enabled" indicates that
       a unit file is permanently enabled.  "enable-runtime" indicates the unit file is only
       temporarily enabled and will no longer be enabled after a reboot (that means, it is
       enabled via /run/ symlinks, rather than /etc/).  "linked" indicates that a unit is linked
       into /etc/ permanently.  "linked-runtime" indicates that a unit is linked into /run/
       temporarily (until the next reboot).  "masked" indicates that the unit file is masked
       permanently.  "masked-runtime" indicates that it is masked in /run/ temporarily (until the
       next reboot).  "static" indicates that the unit is statically enabled, i.e. always enabled
       and doesn't need to be enabled explicitly.  "invalid" indicates that it could not be
       determined whether the unit file is enabled.

       InactiveExitTimestamp, InactiveExitTimestampMonotonic, ActiveEnterTimestamp,
       ActiveEnterTimestampMonotonic, ActiveExitTimestamp, ActiveExitTimestampMonotonic,
       InactiveEnterTimestamp, and InactiveEnterTimestampMonotonic contain CLOCK_REALTIME and
       CLOCK_MONOTONIC 64-bit microsecond timestamps of the last time a unit left the inactive
       state, entered the active state, exited the active state, or entered an inactive state.
       These are the points in time where the unit transitioned "inactive"/"failed" →
       "activating", "activating" → "active", "active" → "deactivating", and finally
       "deactivating" → "inactive"/"failed". The fields are 0 in case such a transition has not
       yet been recorded on this boot.

       CanStart, CanStop, and CanReload encode as booleans whether the unit supports the start,
       stop or reload operations. Even if a unit supports such an operation, the client might not
       necessary have the necessary privileges to execute them.

       CanIsolate encodes as a boolean whether the unit may be started in isolation mode.

       Job encodes the job ID and job object path of the job currently scheduled or executed for
       this unit, if there is any. If no job is scheduled or executed, the job id field will be
       0.

       StopWhenUnneeded, RefuseManualStart, RefuseManualStop, AllowIsolate, DefaultDependencies,
       OnFailureIsolate, IgnoreOnIsolate, IgnoreOnSnapshot map directly to the corresponding
       configuration booleans in the unit file.

       NeedDaemonReload is a boolean that indicates whether the configuration file this unit is
       loaded from (i.e.  FragmentPath or SourcePath) has changed since the configuration was
       read and hence whether a configuration reload is recommended.

       Markers is an array of string flags that can be set using SetUnitProperties() to indicate
       that the service should be reloaded or restarted. Currently known values are
       "needs-restart" and "needs-reload". Package scripts may use the first to mark units for
       later restart when a new version of the package is installed. Configuration management
       scripts may use the second to mark units for a later reload when the configuration is
       adjusted. Those flags are not set by the manager, except to unset as appropriate when the
       unit is stopped, restarted, or reloaded.

       JobTimeoutUSec maps directly to the corresponding configuration setting in the unit file.

       ConditionTimestamp and ConditionTimestampMonotonic contain the
       CLOCK_REALTIME/CLOCK_MONOTONIC microsecond timestamps of the last time the configured
       conditions of the unit have been checked or 0 if they have never been checked. Conditions
       are checked when a unit is requested to start.

       ConditionResult contains the condition result of the last time the configured conditions
       of this unit were checked.

       Conditions contains all configured conditions of the unit. For each condition, five fields
       are given: condition type (e.g.  ConditionPathExists), whether the condition is a trigger
       condition, whether the condition is reversed, the right hand side of the condition (e.g.
       the path in case of ConditionPathExists), and the status. The status can be 0, in which
       case the condition hasn't been checked yet, a positive value, in which case the condition
       passed, or a negative value, in which case the condition failed. Currently only 0, +1, and
       -1 are used, but additional values may be used in the future, retaining the meaning of
       zero/positive/negative values.

       LoadError contains a pair of strings. If the unit failed to load (as encoded in LoadState,
       see above), then this will include a D-Bus error pair consisting of the error ID and an
       explanatory human readable string of what happened. If it loaded successfully, this will
       be a pair of empty strings.

       Transient contains a boolean that indicates whether the unit was created as a transient
       unit (i.e. via StartTransientUnit() on the manager object).

       ActivationDetails contains a list of string pairs, key and value, that describe the event
       that caused the unit to be activated, if any. The key describes the information (e.g.:
       trigger_unit, with value foo.service). This is only filled in if the unit was triggered by
       a Path or Timer unit, and it is only provided in a best effort fashion: it is not
       guaranteed to be set, and it is not guaranteed to be the only trigger. It is only
       guaranteed to be a valid trigger that caused the activation job to be enqueued and
       complete successfully. The key value pairs correspond (in lowercase) to the environment
       variables described in the "Environment Variables Set or Propagated by the Service
       Manager" section in systemd.exec(1). Note that new key value pair may be added at any time
       in future versions. Existing entries will not be removed.

   Security
       Similarly to methods on the Manager object, read-only access is allowed for everyone. All
       operations are allowed for clients with the CAP_SYS_ADMIN capability or when the
       org.freedesktop.systemd1.manage-units privilege is granted by polkit.

SERVICE UNIT OBJECTS

       All service unit objects implement the org.freedesktop.systemd1.Service interface
       (described here) in addition to the generic org.freedesktop.systemd1.Unit interface (see
       above).

           node /org/freedesktop/systemd1/unit/avahi_2ddaemon_2eservice {
             interface org.freedesktop.systemd1.Service {

   Methods
       BindMount() and MountImage() implement the same operations as the respective methods on
       the Manager object (see above). However, these methods operate on the service object and
       hence do not take a unit name parameter. Invoking the methods directly on the Manager
       object has the advantage of not requiring a GetUnit() call to get the unit object for a
       specific unit name. Calling the methods on the Manager object is hence a round trip
       optimization.

   Properties
       Most properties of the Service interface map directly to the corresponding settings in
       service unit files. For the sake of brevity, here's a list of all exceptions only:

       TimeoutStartUSec, TimeoutStopUSec and TimeoutAbortUSec contain the start, stop and abort
       timeouts, in microseconds. Note the slight difference in naming when compared to the
       matching unit file settings (see systemd.service(7)): these bus properties strictly use
       microseconds (and thus are suffixed ...USec) while the unit file settings default to a
       time unit of seconds (and thus are suffixed ...Sec), unless a different unit is explicitly
       specified. This reflects that fact that internally the service manager deals in
       microsecond units only, and the bus properties are a relatively low-level (binary) concept
       exposing this. The unit file settings on the other hand are relatively high-level
       (string-based) concepts and thus support more user friendly time specifications which
       default to second time units but allow other units too, if specified.

       WatchdogTimestamp and WatchdogTimestampMonotonic contain CLOCK_REALTIME/CLOCK_MONOTONIC
       microsecond timestamps of the last watchdog ping received from the service, or 0 if none
       was ever received.

       ExecStartPre, ExecStart, ExecStartPost, ExecReload, ExecStop, and ExecStop are arrays of
       structures where each struct contains: the binary path to execute; an array with all
       arguments to pass to the executed command, starting with argument 0; a boolean whether it
       should be considered a failure if the process exits uncleanly; two pairs of
       CLOCK_REALTIME/CLOCK_MONOTONIC microsecond timestamps when the process began and finished
       running the last time, or 0 if it never ran or never finished running; the PID of the
       process, or 0 if it has not run yet; the exit code and status of the last run. This field
       hence maps more or less to the corresponding setting in the service unit file but is
       augmented with runtime data.

       LimitCPU (and related properties) map more or less directly to the corresponding settings
       in the service unit files except that if they aren't set, their value is
       18446744073709551615 (i.e. -1).

       Capabilities contains the configured capabilities, as formatted with cap_to_text(3).

       SecureBits, CapabilityBoundingSet, MountFlags also correspond to the configured settings
       of the unit files, but instead of being formatted as strings, they are encoded as the
       actual binary flags they are.

       ExecMainStartTimestamp, ExecMainStartTimestampMonotonic, ExecMainExitTimestamp,
       ExecMainExitTimestampMonotonic, ExecMainPID, ExecMainCode, ExecMainStatus contain
       information about the main process of the service as far as it is known. This is often the
       same runtime information that is stored in ExecStart. However, it deviates for
       Type=forking services where the main process of the service is not forked off systemd
       directly. These fields either contain information of the last run of the process or of the
       current running process.

       MainPID and ControlPID contain the main and control PID of the service. The main PID is
       the current main PID of the service and is 0 when the service currently has no main PID.
       The control PID is the PID of the current start/stop/reload process running and is 0 if no
       such process is currently running. That means that ExecMainPID and MainPID differ in the
       way that the latter immediately reflects whether a main process is currently running while
       the latter possible contains information collected from the last run even if the process
       is no longer around.

       StatusText contains the status text passed to the service manager via a call to
       sd_notify(3). This may be used by services to inform the service manager about its
       internal state with a nice explanatory string.

       Result encodes the execution result of the last run of the service. It is useful to
       determine the reason a service failed if it is in the "failed" state (see ActiveState
       above). The following values are currently known: "success" is set if the unit didn't
       fail.  "resources" indicates that not enough resources were available to fork off and
       execute the service processes.  "timeout" indicates that a timeout occurred while
       executing a service operation.  "exit-code" indicates that a service process exited with
       an unclean exit code.  "signal" indicates that a service process exited with an uncaught
       signal.  "core-dump" indicates that a service process exited uncleanly and dumped core.
       "watchdog" indicates that a service did not send out watchdog ping messages often enough.
       "start-limit" indicates that a service has been started too frequently in a specific time
       frame (as configured in StartLimitInterval, StartLimitBurst).

       ControlGroup indicates the control group path the processes of this service unit are
       placed in.

       The following properties map 1:1 to corresponding settings in the unit file: RootDirectory
       RootImage RootImageOptions RootVerity RootHash RootHashSignature MountImages
       ExtensionImages ExtensionDirectories see systemd.exec(5) for their meaning.

       MemoryAvailable indicates how much unused memory is available to the unit before the
       "MemoryMax" or "MemoryHigh" (whichever is lower) limit set by the cgroup memory controller
       is reached. It will take into consideration limits on all parent slices, other than the
       limits set on the unit itself.

       RuntimeDirectorySymlink, StateDirectorySymlink, CacheDirectorySymlink and
       LogsDirectorySymlink respectively implement the destination parameter of the unit files
       settings RuntimeDirectory, StateDirectory, CacheDirectory and LogsDirectory, which will
       create a symlink of the given name to the respective directory. The messages take an
       unused flags parameter, reserved for future backward-compatible changes.

           };

   Properties
       Most of the properties map directly to the corresponding settings in socket unit files. As
       socket units can include ExecStartPre (and similar) fields which contain information about
       processes to execute. They also share most of the fields related to the execution context
       that Service objects expose (see above).

       In addition to these properties there are the following:

       NAccepted contains the accumulated number of connections ever accepted on this socket.
       This only applies to sockets with Accept set to "yes", i.e. those where systemd is
       responsible for accepted connections.

       Similarly NConnections contains the number of currently open connections on this socket.
       It only applies only to socket units with Accept set to "yes".

       Result encodes the reason why a socket unit failed if it is in the "failed" state (see
       ActiveState above). The values "success", "resources", "timeout", "exit-code", "signal"
       and "core-dump" have the same meaning as they have for the corresponding field of service
       units (see above). In addition to that, the value "service-failed-permanent" indicates
       that the service of this socket failed continuously.

       FlushPending specifies whether to flush the socket just before entering the listening
       state. This setting only applies to sockets with Accept= set to "no".

TARGET UNIT OBJECTS

           node /org/freedesktop/systemd1/unit/basic_2etarget {
             interface org.freedesktop.systemd1.Target {
             };
             interface org.freedesktop.DBus.Peer { ... };
             interface org.freedesktop.DBus.Introspectable { ... };
             interface org.freedesktop.DBus.Properties { ... };
             interface org.freedesktop.systemd1.Unit { ... };
           };

       Target units have neither type-specific methods nor properties.

DEVICE UNIT OBJECTS

       All device unit objects implement the org.freedesktop.systemd1.Device interface (described
       here) in addition to the generic org.freedesktop.systemd1.Unit interface (see above).

           node /org/freedesktop/systemd1/unit/dev_2dttyS0_2edevice {
             interface org.freedesktop.systemd1.Device {
               properties:
                 readonly s SysFSPath = '...';
             };
             interface org.freedesktop.DBus.Peer { ... };
             interface org.freedesktop.DBus.Introspectable { ... };
             interface org.freedesktop.DBus.Properties { ... };
             interface org.freedesktop.systemd1.Unit { ... };
           };

   Properties
       Device units only expose a single type-specific property:

       SysFSPath contains the sysfs path of the kernel device this object corresponds to.

MOUNT UNIT OBJECTS

       All mount unit objects implement the org.freedesktop.systemd1.Mount interface (described
       here) in addition to the generic org.freedesktop.systemd1.Unit interface (see above).

           node /org/freedesktop/systemd1/unit/home_2emount {
             interface org.freedesktop.systemd1.Mount {
               methods:
                 GetProcesses(out a(sus) processes);
                 AttachProcesses(in  s subcgroup,
                                 in  au pids);

             interface org.freedesktop.systemd1.Unit { ... };
           };

   Properties
       Most of the properties map directly to the corresponding settings in mount unit files. As
       mount units invoke the /usr/bin/mount command, their bus objects include implicit
       ExecMount (and similar) fields which contain information about processes to execute. They
       also share most of the fields related to the execution context that Service objects expose
       (see above). In addition to these properties there are the following:

       ControlPID contains the PID of the currently running /usr/bin/mount or /usr/bin/umount
       command if there is one running, otherwise 0.

       Result contains a value explaining why a mount unit failed if it failed. It can take the
       values "success", "resources", "timeout", "exit-code", "signal", or "core-dump" which have
       the identical meaning as the corresponding values of the corresponding field of service
       unit objects (see above).

AUTOMOUNT UNIT OBJECTS

       All automount unit objects implement the org.freedesktop.systemd1.Automount interface
       (described here) in addition to the generic org.freedesktop.systemd1.Unit interface (see
       above).

           node /org/freedesktop/systemd1/unit/proc_2dsys_2dfs_2dbinfmt_5fmisc_2eautomount {
             interface org.freedesktop.systemd1.Automount {
               properties:
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly s Where = '...';
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly s ExtraOptions = '...';
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly u DirectoryMode = ...;
                 readonly s Result = '...';
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly t TimeoutIdleUSec = ...;
             };
             interface org.freedesktop.DBus.Peer { ... };
             interface org.freedesktop.DBus.Introspectable { ... };
             interface org.freedesktop.DBus.Properties { ... };
             interface org.freedesktop.systemd1.Unit { ... };
           };

   Properties
       Most of the properties map directly to the corresponding settings in the automount unit
       files.

       Result knows the values "success" and "resources" at this time. They have the same
       meanings as the corresponding values of the corresponding field of the Service object.

TIMER UNIT OBJECTS

       All timer unit objects implement the org.freedesktop.systemd1.Timer interface (described
       here) in addition to the generic org.freedesktop.systemd1.Unit interface (see above).

           node /org/freedesktop/systemd1/unit/systemd_2dtmpfiles_2dclean_2etimer {
             interface org.freedesktop.systemd1.Timer {

                 readonly b RemainAfterElapse = ...;
             };
             interface org.freedesktop.DBus.Peer { ... };
             interface org.freedesktop.DBus.Introspectable { ... };
             interface org.freedesktop.DBus.Properties { ... };
             interface org.freedesktop.systemd1.Unit { ... };
           };

   Properties
       Unit contains the name of the unit to activate when the timer elapses.

       TimersMonotonic contains an array of structs that contain information about all monotonic
       timers of this timer unit. The structs contain a string identifying the timer base, which
       is one of "OnActiveUSec", "OnBootUSec", "OnStartupUSec", "OnUnitActiveUSec", or
       "OnUnitInactiveUSec" which correspond to the settings of the same names in the timer unit
       files; the microsecond offset from this timer base in monotonic time; the next elapsation
       point on the CLOCK_MONOTONIC clock, relative to its epoch.

       TimersCalendar contains an array of structs that contain information about all
       realtime/calendar timers of this timer unit. The structs contain a string identifying the
       timer base, which may only be "OnCalendar" for now; the calendar specification string; the
       next elapsation point on the CLOCK_REALTIME clock, relative to its epoch.

       NextElapseUSecRealtime contains the next elapsation point on the CLOCK_REALTIME clock in
       miscroseconds since the epoch, or 0 if this timer event does not include at least one
       calendar event.

       Similarly, NextElapseUSecMonotonic contains the next elapsation point on the
       CLOCK_MONOTONIC clock in microseconds since the epoch, or 0 if this timer event does not
       include at least one monotonic event.

       Result knows the values "success" and "resources" with the same meanings as the matching
       values of the corresponding property of the service interface.

SWAP UNIT OBJECTS

       All swap unit objects implement the org.freedesktop.systemd1.Swap interface (described
       here) in addition to the generic org.freedesktop.systemd1.Unit interface (see above).

           node /org/freedesktop/systemd1/unit/dev_2dsda3_2eswap {

   Properties
       Most of the properties map directly to the corresponding settings in swap unit files. As
       mount units invoke the swapon(8) command, their bus objects include implicit ExecActivate
       (and similar) fields which contain information about processes to execute. They also share
       most of the fields related to the execution context that Service objects expose (see
       above). In addition to these properties there are the following:

       ControlPID contains the PID of the currently running swapon(8) or swapoff(8) command if
       there is one running, otherwise 0.

       Result contains a value explaining why a mount unit failed if it failed. It can take the
       values "success", "resources", "timeout", "exit-code", "signal", or "core-dump" which have
       the identical meanings as the corresponding values of the corresponding field of service
       unit objects (see above).

PATH UNIT OBJECTS

           node /org/freedesktop/systemd1/unit/cups_2epath {
             interface org.freedesktop.systemd1.Path {
               properties:

             interface org.freedesktop.systemd1.Unit { ... };
           };

   Properties
       Most properties correspond directly with the matching settings in path unit files.

       The others:

       Paths contains an array of structs. Each struct contains the condition to watch, which can
       be one of "PathExists", "PathExistsGlob", "PathChanged", "PathModified", or
       "DirectoryNotEmpty" which correspond directly to the matching settings in the path unit
       files; and the path to watch, possibly including glob expressions.

       Result contains a result value which can be "success" or "resources" which have the same
       meaning as the corresponding field of the Service interface.

SLICE UNIT OBJECTS

       All slice unit objects implement the org.freedesktop.systemd1.Slice interface (described
       here) in addition to the generic org.freedesktop.systemd1.Unit interface (see above).

SCOPE UNIT OBJECTS

       All scope unit objects implement the org.freedesktop.systemd1.Scope interface (described
       here) in addition to the generic org.freedesktop.systemd1.Unit interface (see above).

           node /org/freedesktop/systemd1/unit/session_2d1_2escope {
             interface org.freedesktop.systemd1.Scope {

             interface org.freedesktop.systemd1.Unit { ... };
           };

   Methods
       Abandon() may be used to place a scope unit in the "abandoned" state. This may be used to
       inform the system manager that the manager that created the scope lost interest in the
       scope (for example, because it is terminating), without wanting to shut down the scope
       entirely.

   Signals
       RequestStop is sent to the peer that is configured in the Controller property when systemd
       is requested to terminate the scope unit. A program registering a scope can use this to
       cleanly shut down the processes it added to the scope instead of letting systemd do it
       with the usual SIGTERM logic.

   Properties
       All properties correspond directly with the matching properties of service units.

       Controller contains the bus name (unique or well-known) that is notified when the scope
       unit is to be shut down via a RequestStop signal (see below). This is set when the scope
       is created. If not set, the scope's processes will terminated with SIGTERM directly.

JOB OBJECTS

       Job objects encapsulate scheduled or running jobs. Each unit can have none or one jobs in
       the execution queue. Each job is attached to exactly one unit.

           node /org/freedesktop/systemd1/job/666 {
             interface org.freedesktop.systemd1.Job {
               methods:
                 Cancel();
                 GetAfter(out a(usssoo) jobs);
                 GetBefore(out a(usssoo) jobs);
               properties:
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly u Id = ...;
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly (so) Unit = ...;
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly s JobType = '...';
                 readonly s State = '...';
                 @org.freedesktop.DBus.Property.EmitsChangedSignal("const")
                 readonly a(ss) ActivationDetails = [...];
             };
             interface org.freedesktop.DBus.Peer { ... };
             interface org.freedesktop.DBus.Introspectable { ... };
             interface org.freedesktop.DBus.Properties { ... };
           };

   Methods
       Cancel() cancels the job. Note that this will remove a job from the queue if it is not yet
       executed but generally will not cause a job that is already in the process of being
       executed to be aborted. This operation may also be requested via the CancelJob() method of
       the Manager object (see above), which is sometimes useful to reduce roundtrips.

   Properties
       Id is the numeric Id of the job. During the runtime of a systemd instance each numeric ID
       is only assigned once.

       Unit refers to the unit this job belongs to. It is a structure consisting of the name of
       the unit and a bus path to the unit's object.

       JobType refers to the job's type and is one of "start", "verify-active", "stop", "reload",
       "restart", "try-restart", or "reload-or-start". Note that later versions might define
       additional values.

       State refers to the job's state and is one of "waiting" and "running". The former
       indicates that a job is currently queued but has not begun to execute yet. The latter
       indicates that a job is currently being executed.

       ActivationDetails has the same content as the property of the same name under the
       org.freedesktop.systemd1.Unit interface.

EXAMPLES

       Example 1. Introspect org.freedesktop.systemd1.Manager on the bus

           $ gdbus introspect --system \
                   --dest org.freedesktop.systemd1 \
                   --object-path /org/freedesktop/systemd1

       Example 2. Introspect a unit on the bus

           $ busctl introspect org.freedesktop.systemd1 \
             $(busctl call org.freedesktop.systemd1 \
                /org/freedesktop/systemd1 \
                org.freedesktop.systemd1.Manager \
                GetUnit s systemd-resolved.service | cut -d'"' -f2)

       Example 3. Introspect org.freedesktop.systemd1.Job on the bus

           $ gdbus introspect --system --dest org.freedesktop.systemd1 \
             --object-path /org/freedesktop/systemd1/job/1292
