<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 service is started if <varname>ConditionFirstBoot=yes</varname>
is satisfied. This essentially means that <filename>/etc</filename>
is empty, see
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>
for details.</para>
<para>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 keyboard map</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 by
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>
</refsect1>

<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>
<varlistentry>
<term><option>--keymap=<replaceable>KEYMAP</replaceable></option></term>
<listitem><para>Sets the system keyboard layout. The argument should be a valid keyboard map,
such as <literal>de-latin1</literal>. This controls the <literal>KEYMAP</literal> entry in the
<citerefentry project='man-pages'><refentrytitle>vconsole.conf</refentrytitle><manvolnum>5</manvolnum></citerefentry>
configuration file.</para></listitem>
</varlistentry>
<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>
<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>
file.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>--root-password=<replaceable>PASSWORD</replaceable></option></term>
<term><option>--root-password-file=<replaceable>PATH</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, and
<option>--root-password-file=</option> reads it from a file.
Note that it is not recommended to specify 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>

<term><option>--prompt-root-password</option></term>
<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>
</varlistentry>
<varlistentry>
<term><option>--prompt</option></term>
<listitem><para>Query the user for locale, keymap, timezone, hostname
