nixos-dotfiles

Install on a new system

1. Follow nixos install guide section 2 up to running nixos-install.

2. Edit the generated configuration.nix

   1. Switch user jane with will and add initialPassword option
   2. Add packages neovim and git (others are optional, I usually only install these)
   3. Add this to enable flakes

      nix = {
        packages = pkgs.nixUnstable;
        extraOptions = ''
          experimental-features = nix-command flakes
        '';
        };
      

3. Run nixos-install and set root password when prompted.

   1. If not prompted an error occured.
   2. Good luck

4. Reboot and remove boot drive.

5. Check internet connection.

6. Create new ssh-key with ssh-keygen -t ed25519 -C "[email protected]" and add key to github.

7. eval `ssh-agent` , ssh-add KEYNAME.

8. In home directory run, mkdir dotfiles, cd /dotfiles, git clone [email protected]:SheetKey/nixos-dotfiles.git

9. Create new host file HOSTNAME.nix in /hosts

10. Add to new HOSTNAME.nix

    { config, lib, pkgs, modulesPath, ... }:
    
    {
      networking.howName = "HOSTNAME";
    
      environment.systemPackages = with pkgs; [
      # Add any host specific packages here
      ];
    
      # COPY "system.stateVersion" HERE FROM THE GENERATED "configuration.nix" HERE
    
      # COPY BOOT OPTIONS FROM THE GENERATED "configuration.nix" HERE
    
      # COPY MOST OF FILE FROM THE GENERATED "hardware-configuration.nix" HERE
    
    }
    

11. Edit flake.nix to create new "nixosConfiguration"

    NEWHOSTNAME = lib.nixosSystem {
      inherit system;
    
      modules = [
        ./configuration.nix ./hosts/NEWHOST.nix
        ({ pkgs, ... }: {
          nixpkgs.overlays = [ neovim-nightly-overlay.overlay ]:
        })
    
        home-manager.nixosModules.home-manager {
          home-manager.useGlobalPkgs = true;
          home-manager.useUserPackages = true;
          home-manager.user.will = import ./users/will/home.nix;
          nixpkgs.overlays = [
            nur.overlay emacs-overlay.overlay
          ];
        }
      ];
    };
    

12. Run nix flake lock

13. Build a certain nixosConfiguration.

    nixos-rebuild switch --flake .#NEWHOSTNAME
