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>Scope units are not configured via unit configuration files,
but are only created programmatically using the bus interfaces of
systemd. They are named similar to filenames. A unit whose name
ends in <literal>.scope</literal> refers to a scope unit. Scopes
units manage a set of system processes. Unlike service units, scope
units manage externally created processes, and do not fork off
processes on its own.</para>
<para>The main purpose of scope units is grouping worker processes
of a system service for organization and for managing resources.</para>
<para><command>systemd-run <option>--scope</option></command> may
be used to easily launch a command in a new scope unit from the
command line.</para>
<para>See the <ulink
url="http://www.freedesktop.org/wiki/Software/systemd/ControlGroupInterface/">New
Control Group Interfaces</ulink> for an introduction on how to make
use of scope units from programs.</para>
<para>Unless <varname>DefaultDependencies=false</varname>
is used, scope units will implicitly have dependencies of
type <varname>Conflicts=</varname> and
<varname>Before=</varname> on
<filename>shutdown.target</filename>. These ensure
that scope units are removed prior to system
shutdown. Only scope units involved with early boot or
late system shutdown should disable this option.
