This is something that I'm very much looking forward to see happening. The 3rd point is indeed something that (from my understanding) is not possible. I have thought of an alternative, but that is still a little ugly. Not sure if we want to go that route. - add a new repository with all nfs-ganesha-x.y packages (direct dependencies and sub-packages), without ceph/gluster - add a new repository definition in centos-release-gluster and centos-release-ceph packages. This entry in the .repo file should use the 'exclude=' directive to skip the Ceph sub-package for Gluster, and the Gluster sub-package for Ceph. For additional projects (like Samba) this would work in a similar way. Opinions? Niels
