Dix

Dix is a hardcore challenge for NixOS users: build NixOS each time with nothing more than one line of shell command.

This challenge is inspired by https://github.com/tsoding/Crust.

The Rules of Dix

1. Start with this template Bash command:

NIX_CONFIG="experimental-features=flakes" nixos-rebuild switch --flake $(nix-build --no-out-link --expr 'let nixpkgs = fetchTarball "https://github.com/nixos/nixpkgs/tarball/nixos-unstable"; pkgs = nixpkgs.legacyPackages.x86_64-linux; in pkgs.writeText "flake.nix" "{ inputs.nixpkgs.url = "github:nixos/nixpkgs/nixos-unstable"; outputs = { self, nixpkgs }: { nixosConfigurations.nixos = nixpkgs.lib.nixosSystem { system = \"x86_64-linux\"; modules = [ ({ ... }: { }) ] } } }"')

TODO: this command is written in 10 minutes and not tested, will test in some time

2. Configure your NixOS by editing and running that command in any shell.
3. Shell history will be the only way to store your NixOS configuration.
4. If your configuration becomes missing from the shell history, you have to start over.
5. The configuration cannot read from any file on disk except /nix/store.
6. github:nixos/nixpkgs/nixos-unstable is the only flake input.
7. Fetchers are allowed.
8. Rolling back to a previously built generation is allowed.

The list of rules may change. The goal is to make configuration in NixOS fun.
