** Description changed:

  Test case
  -------------
  - Under Ubuntu 15.04 (or 15.10), set up an unprivileged container as in https://www.stgraber.org/2014/01/17/lxc-1-0-unprivileged-containers/
  - Boot it. You'll get a lot of errors like
  
    [FAILED] Failed to start Journal Service.
    systemd-journald-audit.socket failed to listen on sockets: Operation not permitted
    [FAILED] Failed to listen on Journal Audit Socket.
  
  - The same happens with systemd-nspawn -b.
  
  As a result, the journal isn't working at all, and you have a bunch of
  failed journal related units.
  
  With a fixed systemd package, systemd in the container should realize
  that it cannot listen to the audit socket (as the kernel doesn't allow
  that -- the audit subsystem isn't fit for namespaces right now), and
  "sudo journalctl" should show the journal and systemd-journald.service
  should be running. These systemd fixes are sufficient for nspawn, but
  not completely for unprivileged LXC containers -- there the journal will
  start working, but systemd-journald-audit.socket will still keep failing
  (this is less important)
+ 
+ REGRESSION POTENTIAL: Very low. This only affects the fallback error
+ code path if binding to the audit socket failed. In that case the
+ journal is currently not working at all. This usually doesn't happen on
+ real iron/VMs, so there is no practical change there.
