sorry to be bothering -- i have one more question if anyone's still awake: 1. i bumped ena to 2.4.1: https://gist.github.com/rmcgibbo/7f79562db00f4474db0943fc98fc9c6a 2. i still see `Package ‘ena-2.4.1-5.10.15’ in /nixpkgs/pkgs/os-specific/linux/ena/default.nix:35 is marked as broken, refusing to evaluate.` 3. i can't figure out _who_ marked it as broken or where i can unset that. it doesn't look like it's marked as broken directly in the derivation itself
