We ship the pacemaker-based DLM, yes.
I'd actually not mind following this upstream path too, but I doubt it
can be done in a rolling-upgrade fashion?
Also, is the cman-corosync thing something to stay forever, or is it
just an intermediate step?

That probably answers my question above; so on SLE, we'd skip the 'cman'
bit (and stick to pacemaker's plugin), and then directly go to the
"fully converged upstream" in the next major release.

We just got ourselves a major topic for the conference in October ;-)
