Bug#844785: systemd prevents polkit from working properly

[Raphaël Halimi]

Package: systemd	
Version: 232-1

Since systemd 232, lightdm's menu entries to
shutdown/reboot/suspend/hibernate the system are grayed out.

Furthermore, GNOME polkit authentication agent fails to start (I use
openbox, with the agent normally started from
~/.config/openbox/autostart). When manually run in a terminal, it
immediately exits with the error message:

"polkit-gnome-1-WARNING **: Unable to determine the session we are in:
No session for pid ..."

Downgrading systemd/libsystemd0/libpam-systemd to version 231-10 fixes
the problem (I also tried 232-1 and 232-2, but they didn't work either).

Sorry for the vague bug title (and the probably wrong binary package),
but it's the best I can do since I'm not at all familiar with the way
systemd/polkit/pam/lightdm/whatever interact with each other.

Also, I just spotted this bug today despite the fact that it was
introduced two weeks ago, because I rarely shutdown my sid box.

Regards,
