Nix Configuration

This repository contains Nix configurations for my computers using a modular flake-based architecture.

Usage

Building and Switching

# Using the rebuild script (auto-commits changes)
./rebuild.sh

# Using make commands
make rebuild-nixos    # For NixOS systems
make rebuild-macos    # For Darwin systems
make update           # Update flake inputs
make gc               # Garbage collection

Common Customization

System packages: modules/desktop/packages.nix

GNOME settings: modules/desktop/environment/gnome.nix

User configuration: modules/users/henry/default.nix

Host-specific: modules/hosts/gawain/default.nix

Architecture

• Nix Flakes for reproducible builds
• flake-parts for modular flake composition
• import-tree for automatic module discovery
• Home Manager for user configurations
