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.
