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.

<para>If invoked with no arguments, it applies all directives from

all configuration files. If one or more filenames are passed on

the command line, only the directives in these files are applied.

If only the basename of a configuration file is specified, all

configuration directories as specified in
|

<citerefentry><refentrytitle>tmpfiles.d</refentrytitle><manvolnum>5</manvolnum></citerefentry>

<para>It is possible to combine <option>--create</option>,

|
executed to ensure that all temporary and volatile directories are

|
removed and created according to the configuration file:</para>

<title>Unprivileged --cleanup operation</title>

|
|
|
<para><command>systemd-tmpfiles</command> tries to avoid changing
|
|
the access and modification times on the directories it accesses,
|
|
which requires <constant>CAP_ADMIN</constant> privileges. When
|
|
running as non-root, directories which are checked for files to
|
|
clean up will have their access time bumped, which might prevent
|
|
their cleanup.
