homed.conf, homed.conf.d — Home area/user account manager configuration files
These configuration files control default parameters for home areas/user accounts created and managed by systemd-homed.service(8).
The default configuration is defined during compilation, so a
configuration file is only needed when it is necessary to deviate
from those defaults. By default, the configuration file in
/etc/systemd/ contains commented out entries
showing the defaults as a guide to the administrator. This file
can be edited to create local overrides.
When packages need to customize the configuration, they can install configuration snippets in
The main configuration file is read before any of the configuration directories, and has the lowest
precedence; entries in a file in any configuration directory override entries in the single 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 with
the lexicographically latest name takes precedence. For options which accept a list of values, entries
are collected as they occur in files sorted lexicographically.
/etc/ are reserved for the local administrator, who may use this
logic to override the configuration files installed by vendor packages. It is recommended to prefix all
filenames in those subdirectories with a two-digit number and a dash, to simplify the ordering of the
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
