NixOS is awesome, but contributing to Nixpkgs is at least a little challenging. The tooling leaves a bit to be desired, and it’s really hard to keep all of the guidelines and rules in your head. It would be an excellent experience if there was extensive linting and the tools were easier to understand, imo.

Certainly isn’t an easy problem.

It’s still probably a lot better than contributing to say, Debian. OTOH, the PR backlog is always daunting.
