Adding a new machine

When adding a new machine, you need to write a new host.

1. Make a new directory in the hosts folder
2. Copy the content of /etc/nixos/, into the newly created folder
3. Edit the configuration.nix file, adding settings.nix as an import as such:

  imports =
    [ # Include the results of the hardware scan.
      ./settings.nix
      ./hardware-configuration.nix
    ];

4. Create a settings.nix file with the required fields, here is a minimal setup:

{ config, lib, pkgs, inputs, ... }:

{
  imports = [
    ../../options
  ] ++ [  # Extended settings config (relative folder files ./file.nix)

  ] ++ [  # Include the modules you want to have on this host (from the module folder ../../modules/file.nix)
    ../../common
    ../../modules/home-manager.nix
    ../../modules/home.nix
  ] ++ [  # Include all apps you want to use on this host (from the apps in modules folder ../../modules/apps/file.nix)

  ];

  # Don't need any additional config for the apps, just throw them in here
  environment.systemPackages = with pkgs; [
    discord anki
  ];

  username = "user";
  nickname = "User";
  hostname = "laptop";
  flakeDir = "/home/${config.username}/.dots";
  wms = ["sway"];
}

5. Choose a hostname, and add a new machine in the flake.nix file as follows:

  outputs = { self, nixpkgs, home-manager, ... }@inputs: {

    # Machine1 with hostname "sushi" for example
    nixosConfigurations.sushi = nixpkgs.lib.nixosSystem {
      specialArgs = { inherit inputs; };
      modules = [
        ./hosts/sushi/configuration.nix
        home-manager.nixosModules.home-manager
      ];
    };

    # Machine2 with hostname "taco" for example
    nixosConfigurations.taco = nixpkgs.lib.nixosSystem {
      specialArgs = { inherit inputs; };
      modules = [
        ./hosts/taco/configuration.nix
        home-manager.nixosModules.home-manager
      ];
    };

  };

6. Enter shell nix-shell -p git nh, and do the following command to test it:

   FLAKE=~/.dots nh os test --hostname <HOSTNAME> -- --extra-experimental-features nix-command --extra-experimental-features flakes

7. If everything worked, do FLAKE=~/.dots nh os switch, then reboot.

Adding an existing machine

When adding an existing machine, all you need to do is to overwrite the hardware-configuration.nix found in /etc/nixos with the configuration in the hosts folder.

Then nix-shell -p git nh, entering a shell with git and nh available. Then do the following command to confirm it's working:

FLAKE=~/.dots nh os test --hostname <HOSTNAME> -- --extra-experimental-features nix-command --extra-experimental-features flakes

If it works, then you can apply it with switch:

FLAKE=~/.dots nh os switch --hostname <HOSTNAME> -- --extra-experimental-features nix-command --extra-experimental-features flakes

Then reboot.

Finishing touches

Tune hardware

The setup may not be the same, and so it might be needed to tune the configs such as the sway/hardware.nix

DOOM EMACS

NixOS won't install doom emacs for you, so you have to go to their install instructions for that to be installed: https://github.com/doomemacs/doomemacs?tab=readme-ov-file#install

If you are me

• You need to clone private status command repo to Documents
• Make the ~/.unison/org-files.prf configuration
• Need to make sure the appropriate sops are set
• Set up borg backup (borg.nix)

The configuration is not broken because these things are not added. It's structured to accept both.
