Subject: initctl: support 'telinit u/q'
X-Git-Tag: v33~12
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=46e964c5ce20ce4b46b9187376057081eb71bc55

initctl: support 'telinit u/q'

We send SIGTERM (resp., SIGHUP) when we receive request for changing to
runlevel 'u' (resp., 'q').

As initctl is already async, we just send the signals rather than first
attempting to connect to sytemd over dbus and then falling back to kill.
