Now that the pre-fs ones are run on a transient copy of target/, the
post-fs hooks are no longer needed because we no longer need to restore
the target/ directory as it is only a internal copy.
Remove support for the post-fs hooks, and update the sole package using
them.
We do not add a legacy check because this was mostly a purely-internal
detail that was never really exposed nor documented.

Currently, we handle the factory by redirectoring /var with a symlink at
build time, and with some trickery during the filesystem generation,
depending on whether we need to remount the filesystem read-write or
not.
However, this is causing quite some pain with the latest systemd, now that
they have moved their dbus socket to /run instead of /var/run.
As such, trying to play tricks with /var/run as a symlink is difficult,
because at times it is in .usr/share/factory/var/run (during build) and
then it is in /var/run (at runtime). So a relative symlink is not
possible. But an absolute symlink is not possible either, because we are
installing out-of-tree.
Oh the joys of cross-compilation... :-)
We fix all this mess by making /var a real directory from the onset, so
that we can use the runtime-expected layout even during the build.
Then, during filesystem generation, we move /var away to the factory,
and populate it as we used to do. This still requires a post-fs hook to
restore /var after the filesystem generation.
This leaves a situation that, should the filesystem generation fails,
/var will be left in an inconsistent state. But that is not worse than
what we already had anyway.

When using a RO root with systemd, it is intended that /var/lib should be
populated at boot time by tmpfiles system mirroring it from
/usr/share/factory/var/lib.
However, this will only happen if /var/lib does not already exist at the
time systemd-tmpfiles runs. If it does exist, then tmpfiles will
(silently) skip it and do nothing.
It turns out /var/lib will exist, because some part of systemd creates
/var/lib/systemd/catalog on boot before tmpfiles runs.
The fix used here is to also create tmpfiles entries for the contents of
/var/lib/* and /var/lib/systemd/*. This way, when those directories
already exist, the entire tree is not skipped and instead the
not-yet-existing contents of /var/lib and /var/lib/systemd will be still
be mirrored from the factory dir.
And if /var/lib/systemd, or a prefix of that, stops getting created and
does not exist, it'll still mirror properly.
It does cause some warnings from systemd:
systemd[1]: Starting Create Volatile Files and Directories...
systemd-tmpfiles[148]: [/etc/tmpfiles.d/var-factory.conf:7] Duplicate line for path "/var/lib/systemd", ignoring.
systemd-tmpfiles[148]: [/etc/tmpfiles.d/var-factory.conf:8] Duplicate line for path "/var/lib/systemd/coredump", ignoring.
But they can be ignored.
IMHO, I think a better solution would be for systemd-tmpfiles to gain a
"merge tree" operation that is like "C" but doesn't abort if the
destination exists, but rather merges the source into it.

The skeletons are based on the selection of BR2_INIT_*, so add init- to
the package name to make this clearer. The name skeleton-common implies
that it is common to all skeletons, yet it does not apply to
skeleton-custom. It is only common to the skeleton-init-* packages, so
name it the same way.

The skeletons are based on the selection of BR2_INIT_*, so add init- to

relatively clear, skeleton-common and skeleton-none are less clear on
their relationship to BR2_INIT_*. So rename skeleton-systemd to conform
to clearer pattern.
