That works, but is not the option that we want to provide users. Since updates
happen from UI, we want this to be as seamless as possible.

OVirt users who use nfs option to mount gluster, do use glusterfs-gnfs. And we
had a dependency on glusterfs-gnfs to workaround an earlier bug, so this
package is now available on all hosts.

We want the upgrade from 3.12 to > 4 versions to work. So adding Obsoletes in
glusterfs spec as suggested by others - is this a possible option?
