Whovian's system flake

I needed to put my config into a git repo, so I made my first system config flake (and added my home-manager setup too.) and committed it. If you have suggestions on "fixing" or "cleaning up" my configurations, please add it to the Discussions so I can take a look at it later!

• [githubL:ashebanow Starred - Example Nix Configs] "These are other people's nix configs I've found useful, informative, and/or inspirational."

Extra notes for possible future use:

virtualisation.docker = {
  enableOnBoot = true;
  autoPrune.enable = true;
};

wsl = {
  # Enable integration with Docker Desktop (needs to be installed)
  docker-desktop.enable = false;
};

environment.shells = [pkgs.zsh];

nix = {
  settings = {
    access-tokens = [
      "github.com=${github_token-variable}"
      "gitlab.com=OAuth2:${gitlab_token-variable}"
    ];
    accept-flake-config = true;
    auto-optimise-store = true;
  };

  registry = {
    nixpkgs = {
      flake = inputs.nixpkgs;
    };
  };
  nixPath = [
    "nixpkgs=${inputs.nixpkgs.outPath}"
  ];

  gc = {
    automatic = true;
    options = "--delete-older-than 7d";
  };
};
