It's also impossible to do heartbeat -> pacemaker upgrade without any 
user interaction.

One would get newer rhcs, which would be in universe (well, parts of it 
anyway).

Having automatic configuration merge would be fantastic, but I don't see 
it as a requirement. We are talking about two different products here. 
Did we (desktop) merge pidgin's config when it was replaced? We should 
provide good documentation for that and some of it can be done by simple 
editing of test cases which I wrote 
(https://wiki.ubuntu.com/ClusterStack/LucidTesting).

No, stuff that's in universe is very old and stack changed a lot since 
then. If it stays in universe, we'll lose support for pacemaker both in 
OCFS2 and GFS2. It's main or nothing. Having both crippled pacemaker 
cluster stack and redhat-cluster (which will for sure reach its EOL 
before 10.04 does) would make Ubuntu quite undesirable for fail over 
systems.
