HOMED.CONF(5) homed.conf HOMED.CONF(5)
homed.conf, homed.conf.d - Home area/user account manager
configuration files
/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
These configuration files control default parameters for home
areas/user accounts created and managed by
systemd-homed.service(8).
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
is 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.
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.
systemd(1), systemd-homed.service(8)
1. 💣💥🧨💥💥💣 Please note that those configuration files must
be available at all times. If /usr/local/ is a separate
partition, it may not be available during early boot, and must
not be used for configuration.
