I’m not really keen on upgrading a major distro version unless there is a _really_ compelling reason to do so, especially as we have driver dependencies to Mellanox IB, Lustre, Tesla and Xeon Phi as well as a lot of ISV codes.

One issue hindering me:
kickstart install on machine with infiniband interfaces crashes
