# nixfiles

NixOS / nix-darwin / home-manager configuration for all hosts, built from a
single flake.

## Hosts

Defined in the host table in [`flake.nix`](./flake.nix):

| Configuration       | System          | Machine                                  |
| ------------------- | --------------- | ---------------------------------------- |
| `lyrathorpe-mbp`    | `aarch64-linux` | MacBook Pro (Apple Silicon, Asahi)       |
| `lyrathorpe-x1c`    | `x86_64-linux`  | ThinkPad X1                              |
| `emmathorpe-edaas`  | `x86_64-linux`  | Work WSL box (NixOS-WSL)                 |
| `lyrathorpe-mac`    | `aarch64-darwin`| macOS (nix-darwin)                       |

Shared layers: `lyrathorpe/home` (home-manager: shell, git, editor),
`system/modules/common-nixos.nix` (all NixOS hosts), and
`system/modules/laptop.nix` (the physical laptops).

## Applying

```sh
# NixOS
sudo nixos-rebuild switch --flake .#<configuration>
# Darwin
darwin-rebuild switch --flake .#lyrathorpe-mac
```

## MacBook (Asahi) firmware

The MBP host references `system/modules/firmware/` for Apple peripheral
firmware (Wi-Fi/Bluetooth). Those blobs are **not** redistributable, so the
directory is gitignored and a clean checkout will not build `lyrathorpe-mbp`
until it is populated out-of-band.

Copy the firmware extracted during the Asahi install (from
`/etc/nixos/firmware` on the freshly-installed machine, or re-extract per the
[Asahi NixOS docs](https://github.com/tpwrules/nixos-apple-silicon)) into
`system/modules/firmware/` before rebuilding that host.

## CI

[`.gitea/workflows/ci.yaml`](./.gitea/workflows/ci.yaml) gates `nixfmt`
formatting and evaluates every NixOS and Darwin host configuration on push/PR.
