Ok, I naively assumed that they were synced.
My bad.
A quick check proves me that they are not. :-)


Well, it does not solve the issue.
The emacs-guix popup installed with Guix does not work, neither.

clean ~/.emacs.d
clean ~/.cache
guix package -i emacs-guix
emacs # version 26.1
M-x guix

Then there is issue with the menu. For example the letter p is binded
to processes and also to package.
But it is another story. :-)

Yes for sure. :-)
But when I install ELisp packages with MELPA, then I can easily modify
on-the-fly the code of some function, e.g., change the docstring or
add message or whatever.
Easily because I am just doing `M-x find-function foo' then I edit
`foo' as I want.
When installed with Guix, it is not "so easy" because the ELisp
package lives in the store and it is not a good idea to modify it. So
I need to extract the function, etc.
That's why I prefer MELPA for emacs packages than Guix (or Debian or
whatever) package management. :-)


Thank you for your explanations.

All the best,
simon
