NAME

       homed.conf, homed.conf.d - Home area/user account manager configuration files

SYNOPSIS

           /etc/systemd/homed.conf
           /run/systemd/homed.conf
           /usr/local/lib/systemd/homed.conf
           /usr/lib/systemd/homed.conf
           /etc/systemd/homed.conf.d/*.conf
           /run/systemd/homed.conf.d/*.conf
           /usr/local/lib/systemd/homed.conf.d/*.conf
           /usr/lib/systemd/homed.conf.d/*.conf

DESCRIPTION

       These configuration files control default parameters for home areas/user accounts created
       and managed by systemd-homed.service(8).

CONFIGURATION DIRECTORIES AND PRECEDENCE

The default configuration is set during compilation, so configuration is only needed when
it is necessary to deviate from those defaults. The main configuration file is loaded from
one of the listed directories in order of priority, only the first file found is used:
/etc/systemd/, /run/systemd/, /usr/local/lib/systemd/ [1], /usr/lib/systemd/. The vendor
version of the file contains commented out entries showing the defaults as a guide to the
administrator. Local overrides can also be created by creating drop-ins, as described
below. The main configuration file can also be edited for this purpose (or a copy in /etc/
if it's shipped under /usr/), however using drop-ins for local configuration is
recommended over modifications to the main configuration file.

In addition to the main configuration file, drop-in configuration snippets are read from
/usr/lib/systemd/*.conf.d/, /usr/local/lib/systemd/*.conf.d/, and /etc/systemd/*.conf.d/.
Those drop-ins have higher precedence and override the main configuration file. Files in
the *.conf.d/ configuration subdirectories are sorted by their filename in lexicographic
order, regardless of in which of the subdirectories they reside. When multiple files
specify the same option, for options which accept just a single value, the entry in the
file sorted last takes precedence, and for options which accept a list of values, entries
are collected as they occur in the sorted files.

When packages need to customize the configuration, they can install drop-ins under /usr/.
Files in /etc/ are reserved for the local administrator, who may use this logic to
override the configuration files installed by vendor packages. Drop-ins have to be used to
override package drop-ins, since the main configuration file has lower precedence. It is
recommended to prefix all filenames in those subdirectories with a two-digit number and a
dash, to simplify the ordering. This also defines a concept of drop-in priorities to allow
OS vendors to ship drop-ins within a specific range lower than the range used by users.
This should lower the risk of package drop-ins overriding accidentally drop-ins defined by
users. It is recommended to use the range 10-40 for drop-ins in /usr/ and the range 60-90
for drop-ins in /etc/ and /run/, to make sure that local and transient drop-ins take
priority over drop-ins shipped by the OS vendor.

To disable a configuration file supplied by the vendor, the recommended way is to place a
symlink to /dev/null in the configuration directory in /etc/, with the same filename as
the vendor configuration file.

OPTIONS

       The following options are available in the [Home] section:

       DefaultStorage=
           The default storage to use for home areas. Takes one of "luks", "fscrypt",
           "directory", "subvolume", "cifs". For details about these options, see homectl(1). If
           not configured or assigned the empty string, the default storage is automatically
           determined: if not running in a container environment and /home/ is not itself
           encrypted, defaults to "luks". Otherwise defaults to "subvolume" if /home/ is on a
           btrfs file system, and "directory" otherwise. Note that the storage selected on the
           homectl command line always takes precedence.

           Added in version 246.

       DefaultFileSystemType=
           When using "luks" as storage (see above), selects the default file system to use
           inside the user's LUKS volume. Takes one of "btrfs", "ext4" or "xfs". If not specified
           defaults to "btrfs". This setting has no effect if a different storage mechanism is
           used. The file system type selected on the homectl command line always takes
           precedence.

           Added in version 246.
