This adds /etc/locale.conf to the set of configuration files populated by tmpfiles.d factory /etc handling. In particular, the build-time locale configuration in systemd is now wired to a /usr factory file, and installed to the system. On boot, if other locale customization tools did not write /etc/locale.conf on the system, the factory default file gets copied to /etc by systemd-tmpfiles. This is done in order to avoid skews between different system components when no locale settings are configured. At that point, systemd can safely act as the fallback owner of /etc/locale.conf.

|
|
<para>The <filename>/etc/locale.conf</filename> file configures
|
|
system-wide locale settings. It is read at early boot by
|
|
<citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
|
|
|
|
<para>The basic file format of <filename>locale.conf</filename> is
|
|
a newline-separated list of environment-like shell-compatible
|
|
variable assignments. It is possible to source the configuration
|
|
from shell scripts, however, beyond mere variable assignments, no
|
|
shell features are supported, allowing applications to read the
|
|
file without implementing a shell compatible execution
|
|
engine.</para>
