This useful reference says "GNU Guix1 is a functional package management tool for the GNU system", so it's not a "Distro" as the title here declares? but rather, it's an aptitude replacement via guile? It's always nice to get from protracted video, and odd headline, to: "ok, but what is it? what's its function?"
> Last but not least, Guix is used to build a distribution of the GNU system, with many GNU and non-GNU free software packages. The Guix System Distribution, or GNU GSD, takes advantage of the core properties of Guix at the system level. With GNU GSD, users declare all aspects of the operating system configuration, and Guix takes care of instantiating that configuration in a reproducible, stateless fashion. See GNU Distribution[0].
