Yes, that was the easiest way to make possible to (re)start services 
without the need to reboot.

It could be worked around by adding new command options to the 
cman/gfs/... init scripts:

case "$1" in
   start)
	<check boot option>
	# fall through
   force-start)
	# real startup

I don't know any reliable way to detect it - of course it might be 
possible.

I think the cleanest solution would be to add new command options to the 
init scripts.
