Evaluate plausibility of auto-updates against nixpkgs.

This probably has some major pitfalls, but just thinking that it could be cool to allow rolling-release updates against the latest nixpkgs automatically without needing to update this flake manually. Probably a bad idea... but there's at least the safety-net of autoupgrades not switching to any configuration that fails to apply.

It would seem to require:

[ ] Switch nixosconfigurations to modules in the main flake.
[ ] Implement autoupgrades in the local flake with something like the following:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

    nixos-k3s = {
      url = "github:Avunu/nixos-k3s";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

 outputs = { self, nixpkgs, nixos-k3s }:
  {
    nixosConfigurations = {
      ${builtins.readFile "/etc/hostname"} = nixpkgs.lib.nixosSystem {
        system = "x86_64-linux";
        modules = [
          nixos-k3s.nixosModules.agent
        ];
      };
    };
  };
}
