Future Fedora Releases Likely To Be More Atomic-Like

A. Send and receive?
B. ZFS is out of the question as long as its out of tree. Sun/Oracle made sure of that.
C. IMHO btrfs is not (yet) production quality. It may be there by Fedora 24/25, but its not there yet.

Btrfs and ZFS have a mechanism for pushing filesystem diffs based on subvolume deltas to different file systems. Lennart was saying this would be a mandatory requirement for atomic in his Google+ feed

Code is not the problem. The Nix authors had code a decade ago. Chrome OS had code 5 years ago. Either of those would have been better base update mechanisms than what the distributions were using, and it would have been trivial (although a bit pointless for Nix) to use dpkg/rpm for non-base packages. But, when it comes to widespread adoption, code is less important than being able to control or influence a distribution. The large distributions (Red Hat, Fedora, Debian, Ubuntu etc.) aren't just going to adopt a new distribution model, more so one from an outsider.

Exactly. It is a game of controlling the platform which the rest of the "community" depends on. It may all be free and open source, but it is not a level playing field. Vendors can capitalize a lot easier if they sit directly in the driver seat (or have the drivers under their influence).
