* improve !/proc/*/loginuid situation: make /proc/*/loginuid less dependent on CONFIG_AUDIT,
or use the users cgroup information when /proc/*/loginuid is not available.
+* pam_systemd: try to get old session id from cgroup, if audit sessionid cannot be determined
+
+* logind: auto-suspend, auto-shutdown:
+ IdleAction=(none|suspend|hibernate|poweroff)
+ IdleActionDelay=...
+ SessionIdleMode=(explicit|ignore|login)
+ ForceShutdown=(yes|no)
+
+* logind: use "sleep" as generic term for "suspend", "hibernate", ...
+
* services which create their own subcgroups break cgroup-empty notification (needs to be fixed in the kernel)
* don't delete /tmp/systemd-namespace-* before a process is gone down
