I agree that preventing the combination is the least confusing
solution. I also agree that specifying the conflict for each possible
version is a non-starter.

It provides 'ocfs2'. But so do you.

The fact that you want to have priority over what shipped in
the kernel rpm makes perfect sense. Unfortunately, you're overriding
what's in a separate rpm.

I've been trying to think of ways just to know which is
loaded (eg, having your ocfs2.ko append -elrepo in the string ocfs2
prints at module load time). But I've got nothing that shines.
If I can think of anything, I'll let you know.
