This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.

<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

</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>

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
