Hi, how it works is that RDE is like a big guix configuration. So it makes like a superset of Guix System.

So it can be considered a distro based on Guix if you want, although its just Guix with a channel on the technical side.

Also if you look at the history, guix home was first developed in RDE, and then upstreamed to Guix. So the two projects are very close.
