Nix

Purely functional package manager
Nix is a purely functional package manager. This means that it treats packages like values in purely functional programming languages such as Haskell – they are built by functions that don’t have side-effects, and they never change after they have been built. Nix stores packages in the Nix store, usually the directory /nix/store, where each package has its own unique subdirectory such as
/nix/store/b6gvzjyb2pg0kjfwrjmg1vfhh54ad73z-firefox-33.1/
where b6gvzjyb2pg0… is a unique identifier for the package that captures all its dependencies it’s a cryptographic hash of the package’s build dependency graph. This enables many powerful features.
