Understandable :)  The openais init script is a holdover from prior to 
the corosync/openais split.  Keeping it made upgrading systems from 
openais 0.8.x to corosync 1.x + openais 1.x a bit nicer, but we should 
probably do something about an actual corosync init script.

Correct, not yet possible (although, FWIW, AFAIK, the problems people 
experienced with service ver: 0 generally didn't manifest on SUSE).

I believe adding support for service ver: 1 (MCP) is mostly a matter of 
tweaking the spec file to include the init script and a couple of other 
things, then test it.  See lines 196-198 at:

Patches (or, given it's OBS, submitreqs) gladly accepted :)

Tim
