I don't know about that. The concepts of Nix answer significant deficiencies in the tools you mention. Those tools all assume that you need to build and operate systems, which seems like a lot of effort and overly complex, when the trend is to make all systems throwaway. I've been following Nix for a while, and don't yet have an arena where I can play with it, but the concept is exactly what I think the industry needs. The biggest challenge that I see with nix is that it is basically a new OS and will require a while before many people are comfortable adopting it. Also, it's not Haskell, it's got it's own minimal functional language, Nix, right?
