Let's use the newly gained feature of `busctl` and start is as a
Type=notify unit, which should make sure the unit is started only after
`busctl` is on the bus listening for messages.
This should help with a race spotted in CIs, where we continued too
early after starting `busctl monitor` and miss the emitted signals:

41e4ce06fe shortened existing sleeps, which resulted in the check being
sometimes done before the property had a chance to update. Let's do what
what we do with the rest of the checks and retry it a couple of times.

Otherwise, parsing may unexpectedly succeeds but fail to run writing
.network files with permission error.

As in their current form they didn't work at all:
systemd-timesyncd[190115]: Assertion 's' failed at src/libsystemd/sd-event/sd-event.c:3058, function sd_event_source_set_enabled(). Ignoring.
systemd-timesyncd[190115]: Failed to reenable system ntp server change event source!
systemd-timesyncd[190115]: Failed to enable ntp server defer event, ignoring: Invalid argument
This was also pointed out in the post-merge review [0].
Let's address this together with the rest of the comments, and add
some tests to make sure everything works as it should.

The cleanup uses PERSISTENT_HANDLE while the test uses PERSISTENT, so change
the test to use PERSISTENT_HANDLE so it's cleaned up (i.e. removed from the
tpm) after the test.
When starting a service with a non-root user and a SystemCallFilter and
other settings (like ProtectClock), the no_new_privs flag should not be set.
Also, test that CapabilityBoundingSet behaves correctly, since we need
to preserve some capabilities to do the seccomp filter and restore the
ones set by the service before executing.
Let's wait for the "latest" message systemd-bsod prints to the console
to appear, otherwise we might be too fast and take a console snapshot
before it contains all the information:

- Rename generic_array_bisect_one() -> generic_array_bisect_step(), as there
is also generic_array_bisect_plus_one(), so the original name is confusing.
- Make generic_array_bisect_step() return TEST_GOTO_NEXT or TEST_GOTO_PREVIOUS
when the current array does not contain any matching entries.
- Make generic_array_bisect_step() symmetric with respect to the direction
we are going to, except for the journal corruption handling.
- Make generic_array_bisect_step() gracefully handle journal corruptions,
so the corruption handling in the caller side can be mostly dropped.
- Especially, when the last entry in an array is corrupted, previously
we tried to find a valid entry sequentially from the end of the array,
but now we anyway bisect the array. That should improve performance of
reading corrupted journal files.
- Return earlier when no entry linked to the chained array (n == 0).
- Add many comments.
No behavior change unless journal is corrupted.
Let's put this back in, as it could help with occasional machine lock ups
on overloaded systems (and it didn't help with the original issue
anyway).
This reverts commit 3a89904e45cbbd96fb1c5d0768de5e5fcdaaa508.
Before confext was added, hierarchies always existed in extensions. Now
they are optional - i.e., a sysext will not contain /etc/. So mixing a
confext and a sysext fails, as we'll try to create an overlay with /etc/
from the base, the confext and the sysext, but the latter doesn't have
the directory.
After the source images are mounted, check that each hierarchy exists in
each source image before creating the overlay, and drop them if they
don't.

Introduce a new env variable $SYSTEMD_NSPAWN_CHECK_OS_RELEASE, that can
be used to disable the os-release check for bootable OS trees. Useful
when trying to boot a container with empty /etc/ and bind-mounted /usr/.
Resolves: #29185
When a late error occurs in sd-executor, the cleanup-on-close of the
context structs happen, but at that time all FDs might have already
been closed via close_all_fds(), so a double-close happens. This
can be seen when DynamicUser is enabled, with a non-existing
WorkingDirectory.
Invalidate the FDs in the context structs if close_all_fds succeeds.
