My understanding is that `guix gc --references` reports the references
that it finds by scanning the store item you give as an argument (I
haven't read the code). So, if the packaged software needs to refer to
something but does not, you will not be warned by `guix gc --references`.

From ImageMagick, awesome uses the `convert` tool at build time. I
skimmed the results of `grep -r convert` and I didn't notice any other
uses of the tool, but I might have missed something. Can you
double-check?

Okay.
