you're not concerned about the persistent
lstat("/run/systemd/system/", 0x7fff8173a450) = -1 ENOENT (No such
file or directory)

3.12 is my own, i believe CONFIG_CGROUPS is disabled, yes. to save you
grief i tried debian unstable's very own 3.11-1 and get similar problem
but different issue in :0-greeter.log, billions and billions of:
(gnome-settings-daemon:4938): dconf-CRITICAL **: unable to create
directory '/run/user/0/dconf': Permission denied. dconf will not work
properly.
i think you solved this earlier???????
i will re-roll 3.12 with cgroups and see if i get same thing, this
afternoon.
