Is Nix OS a Proof of Concept?

Nix is like really generally applicable. There's Nix packages, which is a collection of 70,000 packages and it's now 80,000. Configuration stuff is nothing more than a simple package, which we call a file. So that can be used with any Linux distribution or on Mac OS even. If I want to have my whole operating system be controlled through Nix and Nix scripts and Nix packages,. then I can use Nix OS.
