Correct. We still use deb-src as our daily primitive, that's how we update packages and source and it's what we build. Snappy images are just rendered from those binaries similar to the way that ISO images are generated from them.

hi Mark, given that the Docker project already uses snapshots are you planning to be compatible with them.

It would be ultra-cool if I use Ubuntu Core as my server, build a particular configuration that I'm happy with and in a single click is transformed into a Docker package that I can deploy to dozens of machines.

You can use Ubuntu Core, snappy install docker, and then launch your docker containers. All neat and transactional.

What exactly does "neat and transactional" imply? It would be really great if you could provide some technical details to support that statement. I think it would help the announcement, if there existed at least a few words of what's going on and one wouldn't have to go and mine the comments on HN. Sorry, I'm not going to go find and read the source code right now and later I will probably forget about this being a cool thing in the first place, as I wasn't told what exactly is cool about it. Some seem to suggest above that there is a relation/inspiration to Nix, but that's not backed in any way either. Also, once it's a clear response to CoreOS, a detailed comparison would help a lot.

actually, I meant the other way around. Run Ubuntu Core on snappy - you have published KVM images and Azure (!!) images... but not for Docker.

Do you see snappy evolving beyond Ubuntu Core in the future?
