Well, I think there is an issue with the offload. I don't (yet) know
guile well enough to understand the code to help :(
Here is what I am finding: $ guix build blah seems to offload builds
properly. $ guix package -i blah, guix package -u blah, and $ guix
system reconfigure config.scm does not offload builds.
