    <title>Description</title>

    <para>The <filename>/etc/vconsole.conf</filename> file configures
    the virtual console, i.e. keyboard mapping and console font. It is
    applied at boot by udev using <filename>90-vconsole.rules</filename> file.
    You can safely mask this file if you want to avoid this kind of initialization.
    </para>

    <para>The format of <filename>vconsole.conf</filename> is a newline-separated list of environment-like
    shell-compatible variable assignments, ignoring comments and empty lines. 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. See
    <citerefentry><refentrytitle>os-release</refentrytitle><manvolnum>5</manvolnum></citerefentry> for a
    detailed description of the format.</para>

    <para>Note that the kernel command line options
    <varname>vconsole.keymap=</varname>,
    <varname>vconsole.keymap_toggle=</varname>,
    <varname>vconsole.font=</varname>,
    <varname>vconsole.font_map=</varname>,
    <varname>vconsole.font_unimap=</varname> may be used
    to override the console settings at boot.</para>

    <para>Depending on the operating system other configuration files
    might be checked for configuration of the virtual console as well,
    however only as fallback.</para>

    <para><filename>/etc/vconsole.conf</filename> is usually created and updated
    using
    <citerefentry><refentrytitle>systemd-localed.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
    <citerefentry><refentrytitle>localectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
    may be used to instruct <command>systemd-localed.service</command> to
    query or update configuration.</para>

        <varname>KEYMAP_TOGGLE=</varname> can be used to configure a second toggle keymap and is by default
