I think one of the way to implement immutable-toplevel is to add a
config item server.guix. If it's false, then use
default (current-toplevel), otherwise (current-toplevel) returns /gnu/store

Feel free to share your ideas.

My answer is definitly 3, moreover, we should be able to install Artanis
speicific plugins via Guix in the future.
I have to admit that I've given up to write Artanis own package manager
since I won't have any time for that. So Guix will be the most important
package manager in Artanis community.

Yes, please, let's make a plan to integrate Artanis with Guix, and do it!

Thanks!
Best regards.
