GitHub Actions Cache Targets

The cache-targets.toml file contains the build targets for the caching workflow (cache.yml). This allows us to selectively build and push large or important derivations to Cachix so they can be reused.

Each target is defined as a table [[targets]]. Below are the supported properties:

• group (string, required): The category of the target.
  • Examples: "nixos_config_attribute", "nixos_package", "flake_package", "vscode_extensions", "remote_flake".
• name (string, required): The attribute path, package name, or target identifier.
  • Example: "boot.kernelPackages.kernel", "zed-editor", "xdg-desktop-portal-gtk4".
• hostname (string, optional): The target NixOS hostname (required for nixos_config_attribute or nixos_package groups).
  • Example: "Ainz-NIX".
• user (string, optional): The username associated with the target, often used for Home Manager packages or user-specific configurations (like vscode_extensions).
• large_build (boolean, optional): Set this to true if the package takes up a significant amount of disk space to build (e.g., the Linux kernel). When true, the CI will run a specialized setup-nix composite action that aggressively reclaims runner disk space before building. If false or omitted, it defaults to the much faster Determinate Systems Nix installer.
