Ah, I see, so there are several bindings...:)

hmm...OK, so it's dificult to have a partial mirror on my tiny VPS.

Hacking guix itself is... difficult for me, so I expect guix command to work
out of the box:
- invoke "current" guix
- it refers current store (readonly), cloned checkout of guix tree (overriding
  current one), and my local package module
would be desirable.

I've found setting "geiser-guile-load-path" and Autodoc seems to work.
I will try to build environment on this.
