Hello Chrissie,

the buildsystem of lvm2 sill (as of version 2.02.50) doesn't link when
using --with-clvmd=cman,corosync

We plan to move over to stable3 on our test-systems and i'm unsure if i
should switch from cman to corosync for clvmd during the change...

What is the best choice in this case?

What is the value of --with-clvmd on rawhide for cluster3?

What differences we have to expect between these two options?

I think a default value of "auto" for --with-clvmd which uses the best
bindings it could find on a system would be nice...
