    <title>Description</title>

    <para><command>systemd-firstboot</command> initializes the most
    basic system settings interactively on the first boot, or
    optionally non-interactively when a system image is created. The
    following settings may be set up:</para>

    <itemizedlist>
      <listitem><para>The system locale, more specifically the two
      locale variables <varname>LANG=</varname> and
      <varname>LC_MESSAGES</varname></para></listitem>

      <listitem><para>The system time zone</para></listitem>

      <listitem><para>The system host name</para></listitem>

      <listitem><para>The machine ID of the system</para></listitem>

      <listitem><para>The root user's password</para></listitem>
    </itemizedlist>

    <para>Each of the fields may either be queried interactively from
    the users, set non-interactively on the tool's command line, or be
    copied from a host system that is used to set up the system
    image.</para>

    <para>If a setting is already initialized it will not be
    overwritten and the user will not be prompted for the
    setting.</para>

    <para>Note that this tool operates directly on the file system and
    does not involve any running system services, unlike
    <citerefentry project='man-pages'><refentrytitle>localectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>,
    <citerefentry><refentrytitle>timedatectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
    or
    <citerefentry><refentrytitle>hostnamectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
    This allows <command>systemd-firstboot</command> to operate on
    mounted but not booted disk images and in early boot. It is not
    recommended to use <command>systemd-firstboot</command> on the
    running system while it is up.</para>

    <title>Options</title>

    <para>The following options are understood:</para>

    <variablelist>
      <varlistentry>
        <term><option>--root=<replaceable>root</replaceable></option></term>
        <listitem><para>Takes a directory path as an argument. All
        paths will be prefixed with the given alternate
        <replaceable>root</replaceable> path, including config search
        paths. This is useful to operate on a system image mounted to
        the specified directory instead of the host system itself.
        </para></listitem>
      </varlistentry>

      <varlistentry>
        <term><option>--locale=<replaceable>LOCALE</replaceable></option></term>
        <term><option>--locale-messages=<replaceable>LOCALE</replaceable></option></term>

        <listitem><para>Sets the system locale, more specifically the
        <varname>LANG=</varname> and <varname>LC_MESSAGES</varname>
        settings. The argument should be a valid locale identifier,
        such as <literal>de_DE.UTF-8</literal>. This controls the
        <citerefentry project='man-pages'><refentrytitle>locale.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>
        configuration file.</para></listitem>

      <varlistentry>
        <term><option>--timezone=<replaceable>TIMEZONE</replaceable></option></term>

        <listitem><para>Sets the system time zone. The argument should
        be a valid time zone identifier, such as
        <literal>Europe/Berlin</literal>. This controls the
        <citerefentry><refentrytitle>localtime</refentrytitle><manvolnum>5</manvolnum></citerefentry>
        symlink.</para></listitem>
      </varlistentry>

      <varlistentry>
        <term><option>--hostname=<replaceable>HOSTNAME</replaceable></option></term>

        <listitem><para>Sets the system hostname. The argument should
        be a host name, compatible with DNS. This controls the
        <citerefentry><refentrytitle>hostname</refentrytitle><manvolnum>5</manvolnum></citerefentry>
        configuration file.</para></listitem>
      </varlistentry>

        <term><option>--machine-id=<replaceable>ID</replaceable></option></term>

        <listitem><para>Sets the system's machine ID. This controls
        the
        <citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>

        <term><option>--root-password=<replaceable>PASSWORD</replaceable></option></term>

        <listitem><para>Sets the password of the system's root user.
        This creates a
        <citerefentry project='die-net'><refentrytitle>shadow</refentrytitle><manvolnum>5</manvolnum></citerefentry>
        file. This setting exists in two forms:
        <option>--root-password=</option> accepts the password to set
        directly on the command line,
        <option>--root-password-file=</option> reads it from a file.
        Note that it is not recommended specifying passwords on the
        command line as other users might be able to see them simply
        by invoking
        <citerefentry project='die-net'><refentrytitle>ps</refentrytitle><manvolnum>1</manvolnum></citerefentry>.</para></listitem>

        <listitem><para>Prompt the user interactively for a specific
        basic setting. Note that any explicit configuration settings
        specified on the command line take precedence, and the user is
        not prompted for it.</para></listitem>
