I doubt it, unfortunately. I think a Nixos-like approach is the closest you can get to having a single tool, simply because it's a fairly logical extension of apt/rpm/etc.-style systems, but its very operation makes it too alien for me to get it adopted anywhere. I currently suspect that a movement to more PaaS-like designs is actually going to be our saving grace, simply because it ought to take so much off the table. Then we can look at tools like Clojure, Haskell, Prolog, and other similar language concepts to try to tackle the other half of things.
