+* Introduce a way how we can kill the main process of a service with KillSignal, but all processes with SIGKILL later on
+ https://bugzilla.redhat.com/show_bug.cgi?id=952634
+
+* maybe add a warning to the unit file parses whern the acces mode of unit files is non-sensical.
+
+* investigate endianess issues of UUID vs. GUID
+
+* see if we can fix https://bugs.freedesktop.org/show_bug.cgi?id=63672
+ without dropping the location cache entirely.
+
+* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
+ should be able to safely try another attempt when the bus call LoadUnit() is invoked.
+
+* if pam_systemd is invoked by su from a process that is outside of a
+ any session we should probably just become a NOP, since that's
+ usually not a real user session but just some system code that just
+ needs setuid().
