Hey Nathan,

No, it's still in -shim.

Yeah, ignoring the warning is simple, but it's opening a can of worms
indeed as then logind runs into more unimplemented API from -shim. I
wrote an initial (incomplete) patch months ago:

  http://people.canonical.com/~pitti/tmp/0001-Quiesce-warning-about-
missing-user-NNNN.service.patch

but it's not sufficient.

By logind, yes.

That would be wrong (as you can boot with systemd without having the
systemd-sysv package), as well as unnecessary (if user@.service isn't
started, this pam file should be a no-op).

This is ugly indeed, but would be an acceptable SRU for utopic. For
vivid (or possibly in vivid+1 now) we want to switch to systemd for
booting, so it will become unnecessary.

Thanks!

Martin
