## How to add a new host
|
|
|
|
1. Under `hosts/`
|
|
1. Create a new folder under `hosts/` with the name of the new host.
|
|
2. Create & add the new host's `hardware-configuration.nix` to the new folder, and add the new host's `configuration.nix` to `hosts/<name>/default.nix`.
|
|
3. If the new host need to use home-manager, add its custom config into `hosts/<name>/home.nix`.
|
|
1. Under `outputs/`
|
|
1. Add a new nix file named `outputs/<system-architecture>/src/<name>.nix`.
|
|
2. Copy the content from one of the existing similar host, and modify it to fit the new host.
|
|
1. Usually, you only need to modify the `name` and `tags` fields.
|
|
3. [Optional] Add a new unit test file under `outputs/<system-architecture>/tests/<name>.nix` to test the new host's nix file.
|
|
4. [Optional] Add a new integration test file under `outputs/<system-architecture>/integration-tests/<name>.nix` to test whether the new host's nix config can be built and deployed correctly.

|
|
|
|
|
|
|
## Distributed Building
|
|
|
|
I usually run the build command on `Ai` and nix will distribute the build to other NixOS machines, which is convenient and fast.
|
|
|
|
When building some packages for riscv64 or aarch64, I often have no cache available because of various changes under the hood, so I need to build much more packages than usual, which is one of the reasons why the cluster was originally built, and another reason is distributed building is cool!
