Yes


$ ls /usr/share/emacs/site-lisp/site-start.d/
desktop-entry-mode-init.el  git-init.el

$ cat /usr/share/emacs/site-lisp/site-start.d/desktop-entry-mode-init.el
(autoload 'desktop-entry-mode "desktop-entry-mode" "Desktop Entry mode" t)
(add-to-list 'auto-mode-alist '("\\.desktop\\(\\.in\\)?$" .
desktop-entry-mode))

I was expecting something explaining the difference in the fotns sizes. But
that must be somewhere else

Ok, ok, I get it

Note taken. Thanks

For the Fedora Emacs
No Emacs Lisp load-path shadowings were found


 For the Guix Emacs

/home/catonano/.emacs.d/elpa/dash-20151216.1315/dash hides
/home/catonano/.guix-profile/share/emacs/site-lisp/guix.d/dash-2.12.1/dash

3 Emacs Lisp load-path shadowings were found


For both Emacses
"Its value is (zenburn)
Original value was nil"


Look, I installed zenburn with the Fedora Emacs packages machinery, before
even attempting to install Guix

It's in my .emacs.d folder and it's commong among the 2 Emacses

Rather, I'd come up with this hypothesis

The Fedora Emacs is buit against Gtk+ version 3.18.9
The Guix Emacs is built against Gtk+ version 3.18.2

So I read in the respective splash files

Maybe the slight difference in versions might explain the difference in
brightness ?

I have at least an hypothesis now ;-)
