NixOS/nix-darwin configuration

Steps to use

1. Create a new configuration in the machine directory (with a default.nix and a hardware.nix) and symlink the default.nix to /etc/nixos/configuration.nix:

   sudo ln -s machine/<machine>/default.nix /etc/nixos/configuration.nix
       

   If you’re on darwin:

   sudo ln -s machine/<machine>/default.nix $HOME/.nixpkgs/darwin-configuration.nix
       

2. Symlink the overlays:

   sudo ln -s overlays /etc/nixos/overlays
       

   If you’re on darwin:

   sudo ln -s overlays $HOME/.nixpkgs/overlays
       

3. Remove your channels ( I use a fixed version of nixpkgs managed by niv )

   nix-channel --remove <channel_name>
   # the root channel as well
   sudo nix-channel --remove <channel_name>
       

4. Rebuild the nixos configuration:

   nix-shell --run 'rebuild'
       

Structure

• machine - machine configurations
• modules - reusable chunks to build a machine configuration. Includes modules from home-manager and nixos
• overlays - nixpkgs overlays
• pkgs - custom packages that are either not in nixpkgs or are newer versions
• source.* - niv files
