nix configs

my nixos/nix-darwin stuff :)

folder structure

• hosts/ - host-specific configuration
• nixos-modules/ - nixos modules and profiles
• darwin-modules/ - nix-darwin modules
• home-manager/ - home-manager modules
• shared-modules/ - modules shared between nixos and darwin
• lib/ - flake output generation
• secrets/ - agenix secrets

hosts

flake outputs are determined by the hosts/ directory structure. each subdirectory is a host, and the config filename determines the system type:

• configuration.nix → nixos
• darwin-configuration.nix → darwin

option namespaces

custom options live under one root per layer:

• host.* (nixos) - host-level toggles set in configuration.nix:
  • host.profile.* system profiles
  • host.deploy.enable whether its a deploy-rs target
• services.* (nixos/darwin) - custom system services (avoiding upstream collision)
• sam.* (home-manager only) - per-program user config

deployment

hosts with host.deploy.enable = true can be deployed via deploy-rs:

nix develop
deploy .#hostname
