How to add a new host

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.
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.
Under vars/networking.nix
1. Add the new host's static IP address.
2. Skip this step if the new host is not in the local network or is a mobile device.

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!
