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-inhibit</command> may be used to execute a
|
|
program with a shutdown, sleep or idle inhibitor lock taken. The
|
|
lock will be acquired before the specified command line is
|
|
executed and released afterwards.</para>
|
|
|
|
<para>Inhibitor locks may be used to block or delay system sleep
|
|
and shutdown requests from the user, as well as automatic idle
|
|
handling of the OS. This is useful to avoid system suspends while
|
|
an optical disc is being recorded, or similar operations that
|
|
should not be interrupted.</para>
