* support notifications for services being enabled/disabled
+* add support for /bin/mount -s
+
* GC unreferenced jobs (such as .device jobs)
* add JoinControllers= to system.conf to mount certain cgroup
controllers together in order to guarantee atomic creation/addition
of cgroups
+* don't enter "exited" mode for sysv services with pid file
+
* avoid DefaultStandardOutput=syslog to have any effect on StandardInput=socket services
* cgroup_notify_empty(): recursively check groups up the tree, too
* detect LXC environment
+* investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
+
* Maybe store in unit files whether a service should be enabled by default on package installation
(belongs into a distro pattern though, not in an upstream package's service file)
