    <title>Description</title>

    <para><filename>systemd-vconsole-setup</filename> is a helper used to prepare either all virtual consoles, or — if
      the optional <replaceable>TTY</replaceable> parameter is provided — a specific one. When the system is booting up
      it's called by <citerefentry><refentrytitle>systemd-udevd</refentrytitle><manvolnum>8</manvolnum></citerefentry> during vtconsole subsystem initialization.
      <productname>Systemd</productname> also calls it internally as needed via
      <filename>systemd-vconsole-setup.service</filename>. The helper calls
      <citerefentry project='mankier'><refentrytitle>loadkeys</refentrytitle><manvolnum>1</manvolnum></citerefentry> and
      <citerefentry project='die-net'><refentrytitle>setfont</refentrytitle><manvolnum>8</manvolnum></citerefentry>
      internally.
    </para>

    <para>
      You may want to use this helper whenever you change <filename>vconsole.conf</filename> to
      refresh the settings on your consoles — either through the <command>systemctl restart</command> /
      <command>systemctl start</command> command or directly through the executable.
    </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>
