About

This repository accumulates my NixOS configurations.

Inputs are supplied in flake.nix and include:

1. nixpkgs
2. home-manager (follows nixpkgs)
3. kmonad (follows nixpkgs)
4. nix-store-emacs-packages (follows nixpkgs)
5. emacs-overlay

Inputs are mainly used in base-system.nix, that provides basis for my configurations. Included:

1. Nix is configured to use flakes.
2. nixpkgs flake is pinned and added to NIX_PATH to support old nix-shell
3. cachix is added automatically, if cachix.nix exists in its standard location
4. kmonad modules
5. nix-store-emacs-packages and emacs overlays

base-system.nix is imported as a function that takes system type and a list of modules.

Also see this for a flake reference.

Installation

1. Clone the repository (or maybe even fork it?).
2. Write your configuration preferably in the machines directory.
   • Reuse provided modules or write your own.
   • It is also preferable that configuration name matches your machine’s hostname.
3. In the root of the repository run nix run nixpkgs.nixFlakes -c sudo nix --experimental-features 'flakes nix-command' build .#nixosConfigurations.$(hostname).config.system.build.toplevel
4. In the root of the repository run sudo ./result/bin/switch-to-configuration switch
5. Now you can remove ./result
6. Rebuild your system using sudo nixos-rebuild switch --flake <path>#<configuration name>. You can only pass the path, if configuration name matches your hostname.
7. To update all inputs run nix flake update
8. To update single input run nix flake lock --update-input <input name>
9. Don’t forget to commit the lock file.
