    <title>Description</title>

    <para><command>systemd-vconsole-setup</command> sets up and configures either all virtual consoles, or
    — if the optional <replaceable>TTY</replaceable> parameter is provided — a specific one. When the system
    is booting up, <filename>systemd-vconsole-setup.service</filename> is called by
    <citerefentry><refentrytitle>systemd-udevd</refentrytitle><manvolnum>8</manvolnum></citerefentry> during
    VT console subsystem initialization. Also,
    <citerefentry><refentrytitle>systemd-localed.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
    invokes it as needed when language or console changes are made.
    Internally, this program calls
    <citerefentry project='mankier'><refentrytitle>loadkeys</refentrytitle><manvolnum>1</manvolnum></citerefentry>
    and
    <citerefentry project='die-net'><refentrytitle>setfont</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
    </para>

    <para>Execute <command>systemctl restart systemd-vconsole-setup.service</command> in order to apply any manual
    changes made to <filename>/etc/vconsole.conf</filename>.</para>

    <para>See <citerefentry><refentrytitle>vconsole.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry> for
    information about the configuration files and kernel command line options understood by this program.</para>

    <title>Credentials</title>

    <para><command>systemd-vconsole-setup</command> supports the service credentials logic as implemented by
    <varname>ImportCredential=</varname>/<varname>LoadCredential=</varname>/<varname>SetCredential=</varname>
    (see <citerefentry><refentrytitle>systemd.exec</refentrytitle><manvolnum>1</manvolnum></citerefentry> for
    details). The following credentials are used when passed in:</para>

    <variablelist class='system-credentials'>
      <varlistentry>
        <term><varname>vconsole.keymap</varname></term>
        <term><varname>vconsole.keymap_toggle</varname></term>

        <listitem><para>The keymap (and toggle keymap) to apply. The matching options in
        <filename>vconsole.conf</filename> and on the kernel command line take precedence over these
        credentials.</para>

        <para>Note the relationship to the <varname>firstboot.keymap</varname> credential understood by
        <citerefentry><refentrytitle>systemd-firstboot.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>:
        both ultimately affect the same setting, but <varname>firstboot.keymap</varname> is written into
        <filename>/etc/vconsole.conf</filename> on first boot (if not already configured), and then read from
        there by <command>systemd-vconsole-setup</command>, while <varname>vconsole.keymap</varname> is read
        on every boot, and is not persisted to disk (but any configuration in
        <filename>vconsole.conf</filename> will take precedence if present).</para>

        <term><varname>vconsole.font_map</varname></term>
        <term><varname>vconsole.font_unimap</varname></term>

        <listitem><para>The console font settings to apply. The matching options in
        <filename>vconsole.conf</filename> and on the kernel command line take precedence over these
        credentials.</para>
