Sometimes when I log into my GuixSD system, I notice that
/var/guix/profiles/per-user/ambrevar/guix-profile/share/emacs/site-lisp/guix.d
folders are _prepended_ to the path.

Notice that there are two batches of guix.d/* folders: 

	/home/ambrevar/.guix-profile/share/emacs/site-lisp/guix.d/*

and 

	/var/guix/profiles/per-user/ambrevar/guix-profile/share/emacs/site-lisp/guix.d/popup-0.5.3

The former is to be expected, the latter only happens randomly.

I wonder why that is.  I'd rather keep the Guix folders appended so that
they have lower priority than my user-local site-lisp files.

I'm now on Emacs 26.1 RC1 but I had the same issue with Guix' stock package.

De-logging + re-logging usually fixes it.

Any clue?

How are you starting Emacs?  From the command line?  From the GNOME
Activities Overview [1]?  Some other method?  Are you doing anything
"strange" to modify your environment (e.g., running a custom
~/.xsession)?  It matters because the way in which you start a program
can influence the environment in which the program runs, which can in
turn influence the load path of programs like Emacs.

I don't use GNOME, I use EXWM[1] (the Emacs X window manager) which I
start from a custom ~/.xsession with:

	emacs --daemon -f exwm-enable
	exec emacsclient -c

Other than that, I add my local site-lisp to the beginning of my
~/.emacs.d/init.el:

;; We need to roll it out manually since we want it first in the `load-path',
;; while `normal-top-level-add-subdirs-to-load-path' appends it to the very end.
(defun ambrevar/package-refresh-load-path (path)
  "Add every non-hidden sub-folder of PATH to `load-path'."
  (when (file-directory-p path)
    (dolist (dir (directory-files path t "^[^\\.]"))
      (when (file-directory-p dir)
        (setq load-path (add-to-list 'load-path dir))
        (dolist (subdir (directory-files dir t "^[^\\.]"))
          (when (file-directory-p subdir)
            (setq load-path (add-to-list 'load-path subdir))))))))
(let ((site-lisp (expand-file-name "site-lisp/" "~/.local/share/emacs/")))
  (add-to-list 'load-path site-lisp)
