Tom Gundersen 12b42c7667 man: revert dynamic paths for split-usr setups
This did not really work out as we had hoped. Trying to do this upstream
introduced several problems that probably makes it better suited as a
downstream patch after all. At any rate, it is not releaseable in the
current state, so we at least need to revert this before the release.

 * by adjusting the path to binaries, but not do the same thing to the
   search path we end up with inconsistent man-pages. Adjusting the search
   path too would be quite messy, and it is not at all obvious that this is
   worth the effort, but at any rate it would have to be done before we
   could ship this.

 * this means that distributed man-pages does not make sense as they depend
   on config options, and for better or worse we are still distributing
   man pages, so that is something that definitely needs sorting out before
   we could ship with this patch.

 * we have long held that split-usr is only minimally supported in order
   to boot, and something we hope will eventually go away. So before we start
   adding even more magic/effort in order to make this work nicely, we should
   probably question if it makes sense at all.

<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>
<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>

<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,
<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>

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