Oh I see now. Thanks !

Yes, I' d like you to outline the approaches you are referring to. Thanks

Yes, I am running GuixSD. I' m not on a host distro

What I mean is that if I invoke the Emacs Guix commands, they will show the
host guix installation

If I checkout a guix master branch then I can operate it ONLY via the
terminal

What I can do  is launching a REPL with pre-inst.env and then connect to it
from within Emacs and use scheme commands from within Emacs

But I can' t show the beautiful buffers of the Emacs Guix commands in a way
that they refer to a checked out master branch.

So I don' t know how to inspect a package definition, edit it _in place_
and then produce a patch from within guix-emacs

I hope I made the problem clear
