Inspired by https://jade.fyi/blog/flakes-arent-real/, this is better for composability: > it also doesn't work outside of the flake that's actually invoking nixpkgs.lib.nixosSystem. The latter is the much more sinister part, and the reason I would strongly recommend inline modules with closures instead of specialArgs: they break flake composition. For now, the `system` remains a specialArg, until I decide what to do with that.
