Thanks, I've been looking for an excuse to add code to cluster3 to 
disable that mode ;-)

I'm not happy with cman reading groupd tags out of cluster.conf though. 
The alternatives are to have an extra tag for cman, but that risks users 
only setting one or the other and causing havoc. So how about a higher 
level <cluster compat="x"> flag ?
