Description of changes
Sketch out possible requirements document for a holistic approach towards state management in nixos.
This branch is subject to rebase on NixOS/nixpkgs/master.
This branch is in my fork for now, but if there's interest, I'm happy to maintain it within NixOS, in order to allow maintainers to directly write to the documents.
