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><filename>systemd-remount-fs.service</filename> is an
early-boot service that applies mount options listed in
<citerefentry project='man-pages'><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry>
to the root file system, the <filename>/usr</filename> file system,
and the kernel API file systems. This is required so that the
mount options of these file systems — which are pre-mounted by
the kernel, the initial RAM disk, container environments or system
manager code — are updated to those listed in
<filename>/etc/fstab</filename>. This service ignores normal file
systems and only changes the root file system (i.e.
<filename>/</filename>), <filename>/usr</filename> and the virtual
kernel API file systems such as <filename>/proc</filename>,
<filename>/sys</filename> or <filename>/dev</filename>. This
service executes no operation if <filename>/etc/fstab</filename>
does not exist or lists no entries for the mentioned file
systems.</para>
