- implement monitor logic
- properly map matches with well-known names against messages with unique names
- when triggering property change events, allow a NULL strv indicate that all properties listed as such are send out as changed
- - enforce signatures on response messages
- see if we can drop more message validation on the sending side
- support "const" properties as flag
- add API to clone sd_bus_message objects
- support "systemctl stop foobar@.service" to stop all units matching a certain template
- Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
- rework wait filter to not require match callback
- - "systemctl cat" or "systemctl view" command or or so, that cats the backing unit file of a service, plus its drop-ins and shows them in a pager
- better error message if you run systemctl without systemd running
- systemctl status output should should include list of triggering units and their status
- in systemctl list-timers show time trggering units ran last
