 More than four years have passed, and it is likely worth rekindling this discussion, especially now that we actually have a Steering Committee.

+### How large are the packages Hydra would need to additionally store?
+
+`nix-community`'s Hydra instance can give us approximations.
+Its `unfree-redist-full` channel is currently 215G large, including around 200G of NVidia kernel packages and 15G for all the rest of unfree redistributable software.
+Its `cuda` channel is currently 482G large.
+
+It might make sense not to build the cuda/nvidia builds on Hydra for now, at least not before culling a bit the packages, considering there are eg. more than a hundred different NVidia kernel packages.
+Hence, this RFC suggests not setting `runnableOnHydra` for the relevant derivations before cleaning up a bit the NVidia ecosystem in nixpkgs.
