If btrfs builtin command is called, then check if the specified device
node is owned by the device.
This also allows the command is called specifying any device node.
This is useful when the previous invocation is unexpectedly killed.
Otherwise, if systemd-nspawn is killed forcibly, then unix-export
directory is not cleared and unmounted, and the subsequent invocation
will fail. E.g.
```
[ 18.895515] TEST-13-NSPAWN.sh[645]: + machinectl start long-running
[ 18.945703] systemd-nspawn[1387]: Mount point '/run/systemd/nspawn/unix-export/long-running' exists already, refusing.
[ 18.949236] systemd[1]: systemd-nspawn@long-running.service: Failed with result 'exit-code'.
[ 18.949743] systemd[1]: Failed to start systemd-nspawn@long-running.service.
```

The targets that create indicies have
`install : want_html and have_lxml` but some other
code like the `install_symlink` was not gated by
accident.
We ican put the whole loop behind have_lxml as its
required for all the indicies.
lxc tries to mount /sys/fs/cgroup/ following host hierarchy by default,
which is problematic for us since we want to unconditionally use
cgroup v2 in cgns. Disable it hence and let pid1 figure it out.

The log line looked like this:
bootctl[1457]: ! Mount point '/efi' which backs the random seed file is world accessible, which is a security hole! !
which doesn't look nice.
Also upgrade the message to error. This is something to fix.
Admittedly, some of our glyphs _are_ special, e.g. "O=" for SPECIAL_GLYPH_TOUCH ;)
But we don't need this in the name. The very long names make some invocations
very wordy, e.g. special_glyph(SPECIAL_GLYPH_SLIGHTLY_UNHAPPY_SMILEY).
Also, I want to add GLYPH_SPACE, which is not special at all.
Check that when networkd restarts, and the network configures
KeepConfiguration=yes, the network configuration is never changed.
Ensure this by dumping the `ip monitor` output when networkd is restarting.

Then we can detect the error fixed by the previous commit like the following:
../src/libsystemd/sd-device/test-sd-device.c: In function ‘test_sd_device_enumerator_add_all_parents’:
../src/shared/tests.h:225:51: error: comparison of constant ‘0’ with boolean expression is always true [-Werror=bool-compare]

| ^~~~~~~~~
We didn't check the number of arguments first, hence ended up outputting
some ugly complaints with `(null)` in a format string. And what's worse
accepted any number of arguments, where we'd ignore all but the first
two though.
This partially reverts 8d04b8198d.
If we completely drop the file, users will get a 404. But this document
has been in place for a long time and is referred to in many other places,
incl. our old wiki at https://www.freedesktop.org/wiki/Software/.
The page already says that it's been replaced
("… Please consult this document only as a historical reference. …").
We should only remove it from the index (which
8d04b8198d did).
In general, let's be more careful about preserving link stability.
When we change something in a way that breaks URLs, we're creating
pain for users.
This adds a new EMERGENCY_ACTION_SLEEP_5S flag, which when set will
delay the emergency action for 5s. This is supposed to be used together
with EMERGENCY_ACTION_WARN so that users can actually read the message
we output.
We enable this with all emergency action requests that already set
EMERGENCY_ACTION_WARN, except for the 7x ctrl-alt-del burst reboot,
where the user knows what they do and there's no real reason to wait,
they don't need to be informed.
This also enables both EMERGENCY_ACTION_WARN + EMERGENCY_ACTION_SLEEP_5S
for FailureAction= processing of regular units, where these were so far
off. (it leaves this off for SuccessAction= however!). This is a good
thing to make things more debuggable: if something fails and we reboot
this really deserves notification of the user.
(For SuccessAction= this logic does not apply, since the shutdown action
induced here is apparently intended part of the codeflow, for example in
systemd-reboot.service or a similar unit, where the shutdown is goal and
not exception and derserves no additional noisy reporting).
