Can this be put in as a feature request? It doesn't make sense to call a 
node by the name of it's interface. Also cman is more than happy to let 
you put IPs in the <clusternode> and <altname> 'name' attribute (making 
things less ambiguous is always a good thing). But Having to identify 
the node (in crm shell) by the IP address of one of it's interfaces is 
just not right.
