Create app-specific configs (i3.nix, terminal.nix, etc.) -5. Optional: create `variables.nix` for shared color variables - -## Switching Rices - -Rices are assigned per-host in `flake.nix`. Edit the `nixosConfigurations` section: - -```nix -nixosConfigurations = { - kronos = mkSystem "kronos" "nord-blue"; # Laptop uses nord-blue - herra = mkSystem "herra" "cosmic"; # Desktop uses cosmic - mystra = mkSystem "mystra" "nord-blue"; # Another machine uses nord-blue -}; -``` - -Then rebuild: `sudo nixos-rebuild switch` - -Each rice is imported twice: -1. **System-level**: `home/rices/${rice}/system.nix` imported in flake (desktop + stylix) -2. **Home-level**: `home/rices/${rice}` imported in `home/mun/default.nix` via specialArgs (app configs) - -## Important Architecture Details - -**Overlays:** Flake provides `pkgs.unstable.*` for accessing bleeding-edge packages from nixpkgs-unstable while staying on stable 25.11 - -**NixOwOs Integration:** Enabled in `home/mun/default.nix` for NixOS branding/theming (os-release customization, overlays) - -**Machine Separation:** Host configs are intentionally minimal (hostname + hardware-configuration import + optional overrides). All shared system config lives in `system/`, all shared user config in `home/mun/` - -**Rice Architecture:** Rices span both system and home-manager: -- `system.nix` in each rice configures desktop environment (X11 + i3wm) and stylix theming -- `default.nix` in each rice imports home-manager modules (terminal, editor, compositor, etc.) -- System-level desktop/stylix was moved from `system/` to per-rice to allow different DEs per rice - -**Stylix:** System-level theming framework imported at flake level, configured in each rice's `system.nix` (base16 colors, fonts, cursor, opacity, wallpaper) - -**mkSystem Helper:** The `mkSystem` function in flake.nix takes (hostname, rice) and: -1. Imports host config from `hosts/${hostname}/configuration.nix` -2. Imports base system modules from `system/` -3. Imports rice system config from `home/rices/${rice}/system.nix` -4.
