nix-config

Nix configurations for:

• Diamond: Apple silicon macOS, managed with nix-darwin and Malt
• Bort: x86_64 Linux, managed with NixOS and nixpkgs

Organization

The configuration is layered so shared behavior has one owner:

• config/host.nix contains host metadata passed to every system and Home Manager module.
• modules/base contains cross-platform system defaults, shared packages, fonts, user setup, and package policy.
• modules/darwin contains macOS-only nix-darwin settings such as Malt, preferences, and Touch ID.
• hosts/Diamond and hosts/Bort contain machine and desktop policy that should not be shared, such as Paneru, Niri, keyd, services, and hardware.
• home contains the shared Home Manager profile, with platform-specific imports kept next to the affected program.
• flake.nix provides one Home Manager constructor and one system constructor per platform, avoiding duplicated wiring.

Checks and builds

nix fmt
nix build .#darwinConfigurations.Diamond.system
nix build .#nixosConfigurations.Bort.config.system.build.toplevel

For local deployment, use the repository's Justfile targets (just build, just deploy, and just fmt).
