Overlays

Overlays for both NixOS and Nix-Darwin.

If you don't know much about overlays, it is recommended to learn the function and usage of overlays through Overlays - NixOS & Flakes Book.

Current Structure

├── README.md
├── default.nix            # Entrypoint for all overlays
├── computer-use-linux.nix # computer-use-linux from ryan4yin/nur-packages

Components

1. default.nix

The entrypoint imports every overlay file in this directory and applies it to the given arguments.

2. Package overlays

• computer-use-linux.nix: exposes computer-use-linux from the nur-ryan4yin flake input.
• cua-driver.nix: exposes cua-driver from the nur-ryan4yin flake input (used by the computer-use VMs).
• smartctl-exporter/: pins prometheus-smartctl-exporter to the upstream commit carrying PR #329 until nixpkgs provides a version containing the fix; see overlays/smartctl-exporter/default.nix.
