I'm a big fan apart from how they version. Depending on when you install the version will point at a different commit hash. In our case, all of our Haskell builds failed on all but 1 machine (day apart in resolutions). How nixos handles environments meant our large package builds would kill the entire os, or underlying lib linking just failed - never figured out why, but it wasn't worth investing more time.
