Title:
  systemd ships nice.conf override for wrong service

  Triaged

Bug description:
  [Impact]

  Prior to Noble (since Bionic or so), we shipped systemd-
  journald.service with Nice=-1 due to bug 1696970. In Noble, we
  intended to do this with a drop-in config instead of an out-of-tree
  patch [1]. But, this drop-in was mistakenly shipped for systemd-
  logind.service, instead of systemd-journald.service. This means the
  mitigation for bug 1696970 is no longer in place on Noble, and users
  could potentially see regressions.

  [Test]

  Check that systemd-journald.service has Nice=-1 configured (and that
  systemd-logind.service does not):

  $ systemctl show -p Nice systemd-journald.service 
  $ systemctl show -p Nice systemd-logind.service

  [Where problems could occur]

  Clearly, we should be careful that the drop-in is shipped for the
  correct service, otherwise we may apply the setting to the wrong unit.

  [Other information]

  I have not actually seen any regressions reported about this, but as
  we intended to keep the Nice=-1 setting for systemd-journald.service,
  we should restore it.
