> Upstream has been working on adding more btrfs-like features to XFS, but I believe that RHEL encourages using devicemapper snapshots (which you then format with XFS).
Exactly, mountable and mergable snapshots have been supported by a LVM/devicemapper stack for a long time.
It's still a bit more involved than the transparent snapshots ZFS and, to a lesser degree, BtrFS offer. I'm not happy with this and sincerely hope this position changes in the future.
