  44
  45     <para>The <filename>/etc/locale.conf</filename> file configures
  46     system-wide locale settings. It is read at early boot by
  47     <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para>
  48
  49     <para>The basic file format of <filename>locale.conf</filename> is
  50     a newline-separated list of environment-like shell-compatible
  51     variable assignments. It is possible to source the configuration
  52     from shell scripts, however, beyond mere variable assignments, no
  53     shell features are supported, allowing applications to read the
  54     file without implementing a shell compatible execution
  55     engine.</para>

  57     <para>Note that the kernel command line options
  58     <varname>locale.LANG=</varname>,

  70     <varname>locale.LC_MEASUREMENT=</varname>,
  71     <varname>locale.LC_IDENTIFICATION=</varname> may be
  72     used to override the locale settings at boot.</para>
  73
  74     <para>The locale settings configured in
  75     <filename>/etc/locale.conf</filename> are system-wide and are
  76     inherited by every service or user, unless overridden or unset by
  77     individual programs or individual users.</para>
  78
  79     <para>Depending on the operating system, other configuration files
  80     might be checked for locale configuration as well, however only as
  81     fallback.</para>
  82
  83     <para><filename>/etc/vconsole.conf</filename> is usually created and updated
  84     using
  85     <citerefentry><refentrytitle>systemd-localed.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
  86     <citerefentry project='man-pages'><refentrytitle>localectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
  87     may be used to alter the settings in this file during runtime from
  88     the command line. Use
  89     <citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
  90     to initialize them on mounted (but not booted) system images.</para>
