-* do not throw error when .service file is linked to /dev/null
-
* oneshot services which do not remain: 'exited' instead of 'dead'?
it should be visible in 'systemctl' that they have been run
* implicitly import "defaults" settings file into all types
-* "disabled" load state?
-
* ability to kill services? i.e. in contrast to stopping them, go directly
into killing mode?
