Ah, you are ahead of me ;-) I have a patch against initscripts that
passes the correct value, but I have not been able to test it properly
yet so have not pushed it. I'll do it today.

The only reason it's done with $1 rather than $RUNLEVEL is that I
wanted to implement the same interface as systemd/dracut. I guess we
could have fallen back to checking $RUNLEVEL, but (once my patch to
initscripts is in) having $1 not defined means that something is very
wrong, so I thought halting was a nice way to show that.
/me starts testing some patches ;-)
