+* PID1: find a way how we can reload unit file configuration for
+ specific units only, without reloading the whole of systemd
+
+* For services: replace the default Requires=basic.target with After=basic.target + Requires=sysinit.target.
+
+* drop "Overridable" dependency types
+
+* document precise effect of DefaultDependencies=yes
+
+* add an explicit parser for LimitNICE= and LimitRTPRIO= that verifies
+ the specified range and generates sane error messages for incorrect
+ specifications. Also, for LimitNICE= maybe introduce a syntax such
+ as "+5" or "-7" in order to make the limits more readable as they
+ are otherwise shifted by 20.
