* tmpfiles:
- apply "x" on "D" too (see patch from William Douglas)
- - replace F with f+.
- instead of ignoring unknown fields, reject them.
- creating new directories/subvolumes/fifos/device nodes
should not follow symlinks. None of the other adjustment or creation
- <command> <verb> -<TAB> should complete options, but currently does not
- systemctl add-wants,add-requires
-* systemctl status foo.service should say that it is trigger by foo.timer
* systemctl status should know about 'systemd-analyze calendar ... --iterations='
* If timer has just OnInactiveSec=..., it should fire after a specified time
after being started.
