  63
  64     <para><command>systemd-firstboot</command> initializes the most
  65     basic system settings interactively on the first boot, or
  66     optionally non-interactively when a system image is created. The
  67     following settings may be set up:</para>
  68
  69     <itemizedlist>
  70       <listitem><para>The system locale, more specifically the two
  71       locale variables <varname>LANG=</varname> and
  72       <varname>LC_MESSAGES</varname></para></listitem>
  73
  74       <listitem><para>The system time zone</para></listitem>
  75
  76       <listitem><para>The system host name</para></listitem>
  77
  78       <listitem><para>The machine ID of the system</para></listitem>
  79
  80       <listitem><para>The root user's password</para></listitem>
  81     </itemizedlist>
  82
  83     <para>Each of the fields may either be queried interactively from
  84     the users, set non-interactively on the tool's command line, or be
  85     copied from a host system that is used to set up the system
  86     image.</para>
  87
  88     <para>If a setting is already initialized it will not be
  89     overwritten and the user will not be prompted for the
  90     setting.</para>
  91
  92     <para>Note that this tool operates directly on the file system and
  93     does not involve any running system services, unlike
  94     <citerefentry><refentrytitle>localectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>,
  95     <citerefentry><refentrytitle>timedatectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
  96     or
  97     <citerefentry><refentrytitle>hostnamectl</refentrytitle><manvolnum>1</manvolnum></citerefentry>.
  98     This allows <command>systemd-firstboot</command> to operate on
  99     mounted but not booted disk images and in early boot. It is not
 100     recommended to use <command>systemd-firstboot</command> on the
 101     running system while it is up.</para>

 112         <listitem><para>Takes a directory path as an argument. All
 113         paths will be prefixed with the given alternate
 114         <replaceable>root</replaceable> path, including config search
 115         paths. This is useful to operate on a system image mounted to
 116         the specified directory instead of the host system itself.

 127         such as <literal>de_DE.UTF-8</literal>. This controls the

 167         file. This setting exists in two forms:

 169         directly on the command line,
 170         <option>--root-password-file=</option> reads it from a file.
 171         Note that it is not recommended specifying passwords on the
 172         command line as other users might be able to see them simply
 173         by invoking
