Since https://github.com/systemd/systemd/pull/17902/commits/a4a9a6f7c6e9cd9e219c56d08434a04bc2f395ff
systemd improves the detection of Docker and Podman containers based
on the presence of files-markers.
```console
[slev@test systemd]$ git describe --contains --tags a4a9a6f7c6e9cd9e219c56d08434a04bc2f395ff
v248-rc1~155^2~1
```
Note: on Azure unit tests are run as non-privileged user in non-systemd
inited container.
This worked on F32 because:
```console
[root@6d2aad38f62c /]# rpm -q systemd
systemd-245.9-1.fc32.x86_64
```
So, actual comparison in test was `assert None == None`.
But F34 has:
```console
[root@1ff1325f5a61 /]# rpm -q systemd
systemd-248-2.fc34.x86_64
```
So, the test's expectations should be updated.
Unfortunately, this is incompatible with older versions of systemd
(< v248).
See https://github.com/systemd/systemd/pull/17902 for details.
