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.
