Propagating flake inputs

You can propopagate the flake itself into other modules of nixos by using specialArgs:

inputs.nixos-stable.lib.nixosSystem {
    inherit system;
    specialArgs = {
        inherit self inputs;
    };
    ...
    modules = [
        ./modules
    ];
};
...


Now any module in ./modules can have as input attribute `self` and `inputs`
