Emacs load-path random order

[Pierre Neidhardt]

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?
