Moving nix-ros-overlay to nix-community?

[wentasah]

I'm maintaining nix-ros-overlay, which makes ROS (Robot Operating System) available for Nix. We are wondering whether we could move this project to nix-community. The primary driving force behind this is the capacity of the binary cache (free Cachix cache is too small).

ROS is a collection of approximately 1600 packages distributed in multiple (currently 4) versions, called distributions. Our overlay offers two branches: stable and development. Multiplying these numbers gives quite a few derivations, which require about 16 GB in the binary cache. If we add debug outputs (which we currently do not try to cache), we are at 100 GB.

@lopsided98, the owner and previous maintainer agreed with moving the repository.

We have a larger cache (1TB) but it is shared among all projects, we wouldn't allow one project to use 10% of it.

We're planning changes to our cache setup (#1926), I'm hoping to do that in the next month or two, I'd suggest waiting until then.

I was expecting an answer like this :-) In the linked issue, I read that cached paths expire in 1-3 weeks, which is not much different from what happens with our 10 GB free cache. Let's wait.
