I am wondering why Guix chose `/var/guix` path instead of `/gnu/var/guix` or `/guix/var/guix`, as Nix uses `/nix/var/nix`?
I do think that having only one or two directories under root, `/gnu` and/or `/guix` is better, instead of having Guix related files under multiple directories (/var, /run etc.). It will be neat, clean and unique.
