Bug#729134: (no subject)

[dimas]

looking at some neighbourhood bugs, i've found i message by a guy, who used
self-built kernel and thus faced similar problems because of absence of some
systemd-required kernel options and got things working builded new kernel with
everything needed.
this helped for me too. the only problem was that i hadn't config_cgroups
enabled. just builded new kernel today and switched libpam-systemd back on thru
pam-auth-update - and reboot/shutdown is working fine, either in lightdm
greeter or in xfce.

so, if anyone is running custom kernels, check requirements here:
