Hi, I just posted (and ccd you) my setup on another thread. Please let
me know if you have questions.

Yes, this is what happens in a "vanilla" guix installation. You see the
read-only guix code.

I run on a headless server, so I don't have personal experience with a
desktop installation, but I don't believe the limitation you describe
actually exists.

Yes, you can do that. But I don't because I hate typing ;-)

Please try the setup that I posted. I think you will find that it allows
you to do this.
