Not sure if all distros compile it in, but if so, mount.ceph could first try to pass in the DNS name and only do the DNS resolution if the kernel can't. And the kernel client could be updated to remember the DNS name and use that. It's a bit friendlier, but imprecise, since DNS might change. What does NFS do in this case?

Just create a Round Robin DNS record.
