It was also sort of a philosophical question. But anyways ;)

DRBD is one of the few Multi State (or Master Slave or whatever) RA
people actually try to use.

It is my understanding that, because these Master RAs have been less
used/tested, older CRM do not handle them as well as "ordinary" RAs.

I'd like to have a check in there that says: forget it,
this CRM is known to not work as intended with Master RAs.

I'm open for suggestions which version to trigger on,
my intention was to try and say:
heartbeat built-in crm 2.1.4, or pacemaker.

If you say trigger on pacemaker 1.0 is fine, I'd just check on that.

If you say: BS, Master RAs are handled just as well or bad in 2.0.8-SLES10,
ok, I'll just skip this check.
