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-activate</command> can be used to
|
||
launch a socket activated daemon from the command line for
|
||
testing purposes. It can also be used to launch single instances
|
||
of the daemon per connection (inetd-style).
|
||
</para>
|
||
|
||
<para>The daemon to launch and its options should be specified
|
||
after options intended for <command>systemd-activate</command>.
|
||
</para>
|
||
|
||
<para>If the <option>-a</option> option is given, file descriptor
|
||
of the connection will be used as the standard input and output of
|
||
the launched process. Otherwise, standard input and output will be
|
||
inherited, and sockets will be passed through file descriptors 3
|
||
and higher. Sockets passed through <varname>$LISTEN_FDS</varname>
|
||
to <command>systemd-activate</command> will be passed through to
|
||
the daemon, in the original positions. Other sockets specified
|
||
with <option>--listen</option> will use consecutive descriptors.
