    <title>Description</title>

    <para><command>localectl</command> may be used to query and change
    the system locale and keyboard layout settings. It communicates with
    <citerefentry><refentrytitle>systemd-localed</refentrytitle><manvolnum>8</manvolnum></citerefentry>
    to modify files such as <filename>/etc/locale.conf</filename> and
    <filename>/etc/vconsole.conf</filename>.</para>

    <para>The system locale controls the language settings of system
    services and of the UI before the user logs in, such as the
    display manager, as well as the default for users after
    login.</para>

    <para>The keyboard settings control the keyboard layout used on
    the text console and of the graphical UI before the user logs in,
    such as the display manager, as well as the default for users
    after login.</para>

    <para>Note that the changes performed using this tool might require
    the initramfs to be rebuilt to take effect during early system boot.
    The initramfs is not rebuilt automatically by <filename>localectl</filename>.
    </para>

    <para>Note that
    <citerefentry><refentrytitle>systemd-firstboot</refentrytitle><manvolnum>1</manvolnum></citerefentry>
    may be used to initialize the system locale for mounted (but not booted)
    system images.</para>
