I have attached the user config manifest I am currently using. I apply
it with ...

guix package -m g1.scm

... you can also invoke this using the emacs-guix 'M-x guix' popup,
which might be nicer to show in the demo.

I mean that I am running guix from a git checkout. There are a few
different approaches to doing this. I can outline the approach that I
use when you want it.

Hmm, I guess I don't know if you running GuixSD or Guix on another
GNU/Linux OS. I was assuming you are running GuixSD and I was referring
to doing ...

guix system reconfigure sys.scm

If you are running guix/GNU/Linux then you won't be able to include this
in the demo.

Great, sounds like a good plan
