Hi Alex, Thank you for the followup.

I can't test on GuixSD right now, but '2.' looks good here.

If you have a moment, Is there a way to set up my git checkout guix
environment to use changes like this as they are made in the development
version?

My current 'Guix checkout' config (on a Guix/Debian install) looks like
this ...

  /home/g1/.config/guix:
  lrwxrwxrwx 1 g1 g1   14 Mar 24 13:49 latest -> ../../src/guix

... in ~/.profile I have ...

# guix
export GUIX_LOCPATH=$HOME/.guix-profile/lib/locale
GUIX_PROFILE="$HOME/.guix-profile"
source "$HOME/.guix-profile/etc/profile"

... and in ~/.emacs.d/init.el I have ...

;; start: guix emacs setup

;; to run emacs interface from git checkout and have guix-edit operate
;; on git checkout files
(let ((dir "/home/g1/src/guix/emacs"))
  (add-to-list 'load-path dir)
  (setq guix-load-path dir))
(require 'guix-init nil t)

 ;; to read the guix manual from git checkout
(with-eval-after-load 'info
  (info-initialize)
  (add-to-list 'Info-directory-list
               "/home/g1/src/guix/doc"))

;; from #guix for guix compatible diffs
(setq ediff-patch-options "-b -f")

;; end: guix emacs setup

Many thanks, - George
