Recently, I set the “keep-outputs” option in /etc/nix/nix.conf to true. I was surprised to find that, even with this option set, the “dev” and “info” outputs of the version of Guile I have installed (guile-2.2.3) were considered “dead”. It appears that the deriver according to the binary substitute I got from cache.nixos.org does not match the derivation nix reports locally. Can anyone explain why this would be? Additionally, how would I go about getting the deriver in /nix/var/nix/db/db.sqlite to match the store derivation reported by nix-env?
