How to run Guix with Hurd

[fr33d0m]

I'm running a standalone GUIX system and have been updating it with GUIX 
pull and upgrading packages.

I'd like to try running the Hurd instead of Libre-Linux but I don't know 
how to do this.

Can someone help me on how to accomplish this if it's possible to do now?

I'm new to GUIX so don't assume I know much.

Thanks for all the great work you are doing on GUIX!

I plan to create a blog and podcast about what I'm learning to teach 
others about GUIX.
