 Bugfixes:

+* fix emergency mode breakage after the Type=idle change

 
 

-* swap units that are activated by one name but shown in the kernel under another are semi-broken
+* remove MS_SHARED from src/core/execute.c and src/test/test-ns.c. They are always combined
+  with MS_REMOUNT, which currently does nothing in the kernel, but might which fail in the
+  future; https://bugzilla.redhat.com/show_bug.cgi?id=813563

 
 

-* NM should pull in network.target (PENDING)
-  https://bugzilla.redhat.com/show_bug.cgi?id=692008
+* check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar

 
 

-* make anaconda write timeout=0 for encrypted devices
+* swap units that are activated by one name but shown in the kernel under another are semi-broken

 
 

-* service: pid file reading after reload doesn't work, since we don't reset the pid variable
+* make anaconda write timeout=0 for encrypted devices

 
 * make sure timeouts are applied to Type=oneshot services.

+* default unix qlen is too small (10). bump sysctl? add sockopt?

+
+* support "systemctl stop foobar@.service" to stop all units matching a certain template
+
+* logind: allow showing logout dialog from system
+
+* document that %% can be used to write % in a string that is specifier extended
+
+* when an instanced service exits, remove its parent cgroup too if possible.
+
+* as Tom Gundersen pointed out there's a always a dep loop if people use crypto file systems with random keys
+
+* automatically escape unit names passed on the service (i.e. think "systemctl start serial-getty.service@serial/by-path/jshdfjsdfhkjh" being automatically escaped as necessary.
+
+* if we can not get user quota for tmpfs, mount a separate tmpfs instance
+  for every user in /run/user/$USER with a configured maximum size
+
+* default to actual 32bit PIDs, via /proc/sys/kernel/pid_max
+
+* add an option to make mounts private/shareable and so on, enable this for root by default
