Prefer asking pkg-config for the rootlibdir, to also support systems with
--enable-split-usr. Fall back to the hardcoded /usr/lib/systemd if that fails.
./test-dhcp-client would attempt to operate fd 0, i.e. stdin.
For example, './test-dhcp-client </dev/null' would fail with EPERM
because /dev/null cannot be used with epoll.

After all it is now much more like strjoin() than strappend(). At the
same time, add support for NULL sentinels, even if they are normally not
necessary.
When booting with systemd-bootchart, default to call the systemd binary
rather than the init binary on disk, which might be another init system.
Collecting data only works with booting systemd.
On my computer, the minimum brightness enforced by clamping in
backlight is too bright.
Let udev property ID_BACKLIGHT_CLAMP control whether the brightness
is clamped or not.
This patch removes unnecessary blank line in
/usr/lib/tmpfiles.d/etc.conf when configured with "--disable-resolved".
(i.e. ENABLE_RESOLVED is not defined)
From fd.o bug 88898:
systemd-resolved fails to start:
Failed to drop capabilities: Operation not permitted
Broken in f11943c53e.
Drop all capabilities:
1. prctl(PR_SET_KEEPCAPS, keep_capabilities != 0) // 0 when we drop all
capabilities
2. setresuid() // bye bye capabilities
3. Add CAP_SETPCAP // fails because we have no capabilities
4. Reduce capability bounding set
5. Drop capabilities
6. prctl(PR_SET_KEEPCAPS, 0)
Capabilites should always be kept after setresuid() so that the capability
bounding set can be reduced.

We must be careful not to leave PR_SET_KEEPCAPS on. We could use the
setresuid() call to drop capabilities, but the rules when capabilities
are dropped are fairly complex, since a transition to non-zero uid must
happen. Let's instead keep the capabilities during setresuid(), and drop
them later.
If we scale our buffer to be wide enough for the format string, we
should expect that the calculation was correct.
char_array_0() invocations are removed, since snprintf nul-terminates
the output in any case.
A similar wrapper is used for strftime calls, but only in timedatectl.c.
In the test, p is a path to a directory, always absolute. dent->d_name
is a single path component, so they cannot be equal. The comparison
was wrong also for other reasons: D type supports globs, so direct
comparisons using streq are not enough.
Services which are not crucial to system bootup, and have Type=oneshot
can effectively "hang" the system if they fail to complete for whatever
reason. To allow the boot to continue, kill them after a timeout.
In case of systemd-journal-flush the flush will continue in the background,
and in the other two cases the job will be aborted, but this should not
result in any permanent problem.
