Yes, but it only it works for me (glc) because I studied guix for 6
weeks and learned an unpublished trick on #guix IRC channel.

Yes because I am trying to help you improve the user experience. So glc5
is a simulated new user following the manual literally ;)

But what is the _recommended_ way to do this?

A) set 'guix-directory' variable in emacs init file?

B) make symbolic link to ~/src/guix from ~/.config/guix/latest?

C) something else?

And if a _new_ user starts reading in "8.1 Building from Git", how do
they find this information?

FWIW, I vote for method B.
