It's much cleaner now.

I saw sg. in svcadm's man, about marking a service temporarily... which is
in effect until the next reboot.
But, a much simpler solution what I tested:
I started my script with this:

trap 'rm /tmp/x' SIGINT
trap 'rm /tmp/x' SIGTERM

while [ -f /tmp/x ]; do
  sleep 5
done

And here follows your real script.


Before you'd enable again initial-boot, just touch /tmp/x

Maybe not the best workaround, but at least it works! ;)

Cheers,
Gyu
