Well, the scenario I outlined assumed running from a 'guix git checkout'
because I had the impression that you were running that way. But it may
be overkill for many users and it really might be better to create a
demo using a 'guix pull' setup. This could focus on using emacs-guix to
find, build, install, and inspect packages. It could also demonstrate
editing the system config, reconfiguring the system, creating a user
manifest and running 'guix package -m user.scm' Such a demo would be
very cool and immediately relevant to anyone that has just installed
guix or guixSD.

I followed a scenario like the one I fist outlined to figure out why
emacs running in a terminal using screen had only 16 colors and how to
fix it and submit a patch to make it have 256 colors. So I guess you
could use that if you want to run from a terminal. But a better choice
might be a package where you can see the results of a config change on
the command line in an emacs shell buffer.

I hope someone reading this will suggest such a package ;-)

Right. And I am happy to share my git checkout config with you if that
would help.

But... would you want to first do the 'git pull' based demo?
