Funny thing is that if ZFS happens in Docker it'll be only because the community demanded it over the opposition of the core Docker maintainers. AFAICT, Aufs is being dropped due to massive opposition from Redhat. (Apparently AUFS code is too horrible to merge/support???) Despite its spotty track record, BTRFS is the only current recommended/supported CoW file system, and OverlayFS looks to be the docker-blessed next-gen Aufs alternative. Based on past experiences, I don't see Docker-blessed ZFS support coming anytime soon, but I hope I'm wrong. Maybe someone over at Joyent or Oracle can grease the wheels here? :-)
