Good point, thank you.

Control: retitle -1 no consolekit session available when libpam-systemd is present

I'll ask upstream about that. Also, we might want to push it to
experimental (or even unstable, at that point) and check for any
fallouts.

happen with an unpatched lightdm and libpam-systemd?
