The current code -9 is not sufficient unfortunately.

upstart does not use (or for that matter create) /dev/initctl, so the check
if [ ! -p $INITCTL ]
will be true when upstart is installed and the SIGUSR1 signal sent to pid 1.

So I'd appreciate if the additional check "&& [ ! -x /sbin/initctl ]" would be
added. It ensures that this code is not run with upstart (and it is not needed
anyway with upstart).

If it could be removed altogether, even better.
But I'm not qualified to answer that.
