There is also `guix describe` which allows others to completely
reproduce your environment.

So these are all parts of Guix itself. Can you compare a couple of these
non-reproducible pairs of files and reply with the differences here?

Some useful tools available from Guix are diffoscope and vbindiff.

Since they are all part of Guix and using Guile I think the issue will
be the same for all of them.
