bromanko's Nix Configuration

This is my Nix configuration. It supports my macOS, nixOS, and home-manager configurations.

Usage

Requirements

Nix and Flakes must be installed in order to build the derivations. I recommend using the Determinate Nix Installer.

curl --proto '=https' --tlsv1.2 -sSf -L \
  https://install.determinate.systems/nix | sh -s -- install

Building and Applying

You can now build a system configuration by running nix build and specifying the configuration target:

For nix-darwin (macOS):

nix build .#darwinConfigurations.bromanko-personal-mbp.system
./result/sw/bin/darwin-rebuild switch --flake .#bromanko-personal-mbp

For nixos:

nixos-rebuild switch --flake .#nixosConfigurations.dev-vm

For home-manager:

nix build .#homeManagerConfigurations.fb-devserver.activationPackage
./result/activate

For a LiveCD:

[!NOTE] These ISOs must be built on a Linux system.

nix build .#isoConfigurations.macmini.config.system.build.isoImage

Home Manager Configuration

The home-manager configuration is decoupled from the nixos or Darwin modules. This allows me to use the same config for both environments managed by nixos/nix-darwin and plain home-manager. Unfortunately it makes the organization of modules messy. The modules defining home-manager options must be in separate files from the config itself. This is because I need to import the home-manager config manually outside of the module loading process.

• The /home-manager folder contains the home-manager config and will get imported under a home-manager option.
• The /modules/home-manager folder contains the options for enabling home-manager configuration.
