[Bug 1206897] [NEW] logind fails to work, falling back to ConsoleKit when /run/users already exists

[Robert Ancell]

Public bug reported:

When testing Mir I've found a case where logind fails and this causes
the user to lose access the hardware accelerated rendering. The cause is
(for some unknown reason) /run/user exists and logind aborts when trying
to open a session.

>From /var/log/auth.log:

Jul 31 13:25:07 alchemy lightdm: pam_unix(lightdm:session): session opened for user bob by (uid=0)
Jul 31 13:25:07 alchemy systemd-logind[725]: Failed to create /run/user: File exists
Jul 31 13:25:07 alchemy lightdm: pam_systemd(lightdm:session): Failed to create session: File exists

When this first occurred it would persist between reboots and went away
eventually (don't know if I did anything to cause that).

The second time it occurred I did:
$ sudo stop lightdm
$ sudo umount /run/user
$ sudo rmdir /run/user
$ sudo start lightdm

and this fixes the problem.
