Bug description:
  systemd autopkgtests are failing in kinetic, and they are not
  considered regressions. The failing test is one within networkd-
  test.py:

  ======================================================================
  ERROR: test_resolved_domain_restricted_dns (__main__.DnsmasqClientTest)
  resolved: domain-restricted DNS servers
  ----------------------------------------------------------------------
  Traceback (most recent call last):
    File "/tmp/autopkgtest.wTrLDQ/build.Oa5/src/test/networkd-test.py", line 680, in test_resolved_domain_restricted_dns
      out = subprocess.check_output(['resolvectl', 'query', 'math.lab'])
    File "/usr/lib/python3.10/subprocess.py", line 420, in check_output

      raise CalledProcessError(retcode, process.args,
  subprocess.CalledProcessError: Command '['resolvectl', 'query', 'math.lab']' returned non-zero exit status 1.

  ----------------------------------------------------------------------
  Ran 35 tests in 161.770s

  FAILED (errors=1, skipped=2)

  The failures started without any changes to the systemd package, i.e.
  it was caused by another package upload. In particular, the failures
  started around 2022-11-17 with linux 5.19.0-24.25. The tests pass fine
  with linux 5.19.0-21.21, i.e. the version in kinetic-release.

  This can be demonstrated locally with autopkgtest:

  $ autopkgtest --shell-fail systemd --test-name networkd-test.py --pin-
  packages=kinetic=src:linux --setup-commands 'apt update' -- qemu
  /home/nr/ubuntu/autopkgtest-testbeds/autopkgtest-kinetic-amd64.img

  Note in the above command I did not pass -U, so no packages in the
  test bed are upgraded. But, with:

  $ autopkgtest --shell-fail systemd --test-name networkd-test.py -U --
  qemu /home/nr/ubuntu/autopkgtest-testbeds/autopkgtest-kinetic-
  amd64.img

  the kernel is upgraded, and the test fails.

  This can also be done manually by grabbing the systemd source on a
  kinetic machine (e.g. pull-lp-source systemd kinetic), and running:

  $ sudo python3 test/networkd-test.py
  DnsmasqClientTest.test_resolved_domain_restricted_dns

  The attached journal.txt shows systemd-resolved logs from when the
  test is run. The failure is caused by the EHOSTUNREACH when trying to
  resolve math.lab.
