[Bug 1457054] [NEW] journal is broken in unprivileged LXC and nspawn containers

 

Public bug reported:

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.

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.
