I frequently encounter trivially broken packages on nixpkgs. I usually rebuild them with
NIXPKGS_ALLOW_BROKEN=1 and then fix them based on the error message that I see. But presumably this error message already exists somewhere, e.g. on hydra, when the build was originally flagged as broken. Is there a quick way to get it? Could the link to the failing build log be displayed directly in the broken package message that Nix emits? I have the feeling that this would greatly encourage me to fix trivially broken packages because I could recognize them instantly as such.
