If you make a change to your cider recipe, then the "relics" can't
interfere with later builds, because the new cider directory in
/gnu/store will have a new hash. It is impossible for the build process
to guess the hash of the old cider "relics", so they won't be used.

If you don't change the cider recipe, then the relics will be used.
