Comment 4 for bug 1351306

Wrt. runlevel, telinit, shutdown, poweroff, halt: i think we want upstart equivalent to be aware of systemd. Such that, if system was booted with systemd, one can use invoke upstart commands which will send the request off to e.g. systemctl,

Similarly, we probably want to continue to provide "start/stop/restart/reload" commands that also call into systemctl if appropriate.
