NAME

       systemd.scope - Scope unit configuration

SYNOPSIS

       scope.scope

DESCRIPTION

       Scope units are not configured via unit configuration files, but are only created
       programmatically using the bus interfaces of systemd. They are named similar to filenames.
       A unit whose name ends in ".scope" refers to a scope unit. Scopes units manage a set of
       system processes. Unlike service units, scope units manage externally created processes,
       and do not fork off processes on its own.

       The main purpose of scope units is grouping worker processes of a system service for
       organization and for managing resources.

       systemd-run --scope may be used to easily launch a command in a new scope unit from the
       command line.

       See the New Control Group Interfaces[1] for an introduction on how to make use of scope
       units from programs.

       Note that, unlike service units, scope units have no "main" process: all processes in the
       scope are equivalent. The lifecycle of the scope unit is thus not bound to the lifetime of
       one specific process, but to the existence of at least one process in the scope. This also
       means that the exit statuses of these processes are not relevant for the scope unit
       failure state. Scope units may still enter a failure state, for example due to resource
       exhaustion or stop timeouts being reached, but not due to programs inside of them
       terminating uncleanly. Since processes managed as scope units generally remain children of
       the original process that forked them off, it is also the job of that process to collect
       their exit statuses and act on them as needed.

AUTOMATIC DEPENDENCIES

   Implicit Dependencies
       Implicit dependencies may be added as result of resource control parameters as documented
       in systemd.resource-control(5).

   Default Dependencies
       The following dependencies are added unless DefaultDependencies=no is set:

       ยท   Scope units will automatically have dependencies of type Conflicts= and Before= on
           shutdown.target. These ensure that scope units are removed prior to system shutdown.
           Only scope units involved with early boot or late system shutdown should disable
           DefaultDependencies= option.

OPTIONS

       Scope files may include a "[Scope]" section, which carries information about the scope and
       the units it contains. A number of options that may be used in this section are shared
       with other unit types. These options are documented in systemd.kill(5) and
       systemd.resource-control(5). The options specific to the "[Scope]" section of scope units
       are the following:

       RuntimeMaxSec=
           Configures a maximum time for the scope to run. If this is used and the scope has been
           active for longer than the specified time it is terminated and put into a failure
           state. Pass "infinity" (the default) to configure no runtime limit.
