Judging by https://launchpad.net/~upstream-systemd-ci/+archive/ubuntu/systemd-ci/+packages,
it got updated about 15 hours ago and the "build check" action has been
failing with
```
The following packages have unmet dependencies:
kbd : Depends: console-setup but it is not going to be installed or
E: Unable to correct problems, you have held broken packages.
console-setup-mini but it is not going to be installed
```
since then
Read-only /var/tmp is more likely, because it's backed by a real device. /tmp
is (by default) backed by tmpfs, but it doesn't have to be. In both cases the
same consideration applies.
If we boot with read-only /var/tmp, any unit with PrivateTmp=yes would fail
because we cannot create the subdir under /var/tmp to mount the private directory.
But many services actually don't require /var/tmp (either because they only use
it occasionally, or because they only use /tmp, or even because they don't use the
temporary directories at all, and PrivateTmp=yes is used to isolate them from
the rest of the system).
To handle both cases let's create a read-only directory under /run/systemd and
mount it as the private /tmp or /var/tmp. (Read-only to not fool the service into
dumping too much data in /run.)
$ sudo systemd-run -t -p PrivateTmp=yes bash
Running as unit: run-u14.service

This commit has more changes than I like to put in one commit, but it's touching all
the same paths so it's hard to split.
exec_runtime_make() was using the wrong cleanup function, so the directory would be
left behind on error.
Let's add a catalog entry explaining further details.
Most importantly though: talk to PID 1 directly, via the private D-Bus
socket, so that this actually works correctly during early boot, where
D-Bus is not around.
Apparently systemd is no longer installed in fedora containers
by default
```
docker: Error response from daemon: OCI runtime create failed: container_linux.go:348:
starting container process caused "exec: \"/sbin/init\": stat /sbin/init: no such file or directory": unknown.
The command "$CI_MANAGERS/fedora.sh SETUP" failed and exited with 127 during .

The test would always fail with a long uname. In F33 this is right
now "5.8.0-0.rc2.20200622git625d3449788f.1.fc33.x86_64" which caused the
test to always fail.
Commit b0ca726585 "rpm: avoid hiding errors from systemd commands" remove hiding errors and output
for other macros, but did not do that for %sysusers_create_package and %tmpfiles_create_package.
This change syncs their behaviour with %sysusers_create and %tmpfiles_create

The last line in this macros was actually "SYSTEMD_INLINE_EOF " with a space at the end,
but the shell was instructed to look for a line without space.
Macros %sysusers_create_inline and %tmpfiles_create_inline did not have this mistake.
An example:
[root@rosa-2019 bind-server]# cat /etc/passwd | grep named
[root@rosa-2019 bind-server]# cat /tmp/bs
systemd-sysusers --replace=/usr/lib/sysusers.d/named.conf - <<SYSTEMD_INLINE_EOF >/dev/null 2>&1 || :
u named - "BIND DNS Server" /var/lib/named
g named - -
m named named
SYSTEMD_INLINE_EOF
[root@rosa-2019 bind-server]# sh /tmp/bs
/tmp/bs: line 5: warning: here-document at line 1 delimited by end-of-file (wanted `SYSTEMD_INLINE_EOF')
[root@rosa-2019 bind-server]# bash /tmp/bs
/tmp/bs: line 5: warning: here-document at line 1 delimited by end-of-file (wanted `SYSTEMD_INLINE_EOF')
[root@rosa-2019 bind-server]# bash --version
GNU bash, version 5.0.17(1)-release (x86_64-openmandriva-linux-gnu)
The user and group named were NOT created!
Now I remove the trailing space after "SYSTEMD_INLINE_EOF" and rerun:
[root@rosa-2019 bind-server]# sh /tmp/bs
[root@rosa-2019 bind-server]# tail -n 1 /etc/group
named❌485:named
[root@rosa-2019 bind-server]#
The user and group have been created correctly.

Currently systemd-user-runtime-dir does not create the files in
/run/user/$UID/systemd/inaccessible with the default SELinux label.
The user and role part of these labels should be based on the user
related to $UID and not based on the process context of
systemd-user-runtime-dir.
Since v246-rc1 (9664be199a) /run/user/$UID/systemd is also created by
systemd-user-runtime-dir and should also be created with the default
SELinux context.
This commit enables the microphone mute button and the screen rotate button, even if the latter is improperly linked. I have documented how to achieve this in https://wiki.archlinux.org/index.php/MSI_P15#Fn_Keys .
We never return anything higher than 63, so using "long unsigned"
as the type only confused the reader. (We can still use "long unsigned"
and safe_atolu() to parse the kernel file.)
We would refuse to print capabilities which were didn't have a name
for. The kernel adds new capabilities from time to time, most recently
cap_bpf. 'systmectl show -p CapabilityBoundingSet ...' would fail with
"Failed to parse bus message: Invalid argument" because
capability_set_to_string_alloc() would fail with -EINVAL. So let's
print such capabilities in hexadecimal:
CapabilityBoundingSet=cap_chown cap_dac_override cap_dac_read_search
cap_fowner cap_fsetid cap_kill cap_setgid cap_setuid cap_setpcap
cap_linux_immutable cap_net_bind_service cap_net_broadcast cap_net_admin
cap_net_raw cap_ipc_lock cap_ipc_owner 0x10 0x11 0x12 0x13 0x14 0x15 0x16
0x17 0x18 0x19 0x1a ...
For symmetry, also allow capabilities that we don't know to be specified.

The call would always fail with:
systemd-userwork[780]: Failed to dlopen(libnss_systemd.so.2), ignoring: /usr/lib64libnss_systemd.so.2: cannot open shared object file: No such file or directory
For some reason the wait-online is failing intermittently; it's unclear
exactly why, but this hopefully avoids the failure for unrelated PR.
This is a workaround (not fix) for #16105
