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.
