Great, thanks.

However, while this change might avoid the problem with guix pull in the
future, I still a bit stuck. I got this from a fresh install of Guix on
the Overdrive machine I have (aarch64-linux).

I'm hoping that I'll be able to install git and the Guix dependencies,
download the repository, and then get a newer version of Guix that way,
but I'm guessing this will still be a problem for other aarch64-linux
machines unless there's a substitute out there somewhere.
