You're welcome! Thanks for the review. I wish I had more time to
contribute to Guix.

I suppose I should have qualified my statement by saying there's too
many dependent Go packages for me to test. I should invest in a better
computer :)

Spot on! I've updated docker and docker-cli. hyperledger-fabric depends
on docker-cli and also continues to build. I've attached a patch which
should supersede the prior patch. It updates go, docker, and docker-cli
atomically.

Agreed.

I believe 1.14 represents a stabilization of the modules feature, so I
would expect future updates to go smoothly as well.

`guix lint` now complains about downloading tarballs. I have also
recently seen some chatter on the mailing list about preferring this.
