NixOS & nix-darwin Configurations

This repository houses my NixOS and macOS (nix-darwin) configurations. The system loader lives in lib/loadSystems.nix and lib/mkSystem.nix, with per-host configs under systems/ and user config under home-manager/.

Structure

• systems/base/: shared defaults for Linux and Darwin
• systems/<hostname>/: per-host overrides (current host: m4mbp)
• home-manager/<user>/: shared user config and per-host overlays
• modules/: reusable Nix modules
• overlays/ + pkgs/: custom overlays/packages

Common Commands

• make lint: run deadnix, nixpkgs-fmt, and statix (same as pre-commit)
• make check: run lint + nix flake check --all-systems, then build the current host
• make or make switch: build and switch the current host (Darwin uses darwin-rebuild switch)
• make test: NixOS test build (Linux only)

Current Systems

• m4mbp — Apple Silicon MacBook Pro running nix-darwin

The repo remains multi-system capable (aarch64/x86_64, Linux/Darwin) for future hosts.
