Indeed.

Well, it seems that the main issue is that Guix honors the same
environment variables as Nix, which causes confusion.

We should probably fix it.

I=E2=80=99d rather avoid per-distro sections.  The =E2=80=9CApplication Set=
up=E2=80=9D section
is meant to contain all the hints for using Guix on a =E2=80=9Cforeign dist=
ro=E2=80=9D,
and those hints should be pretty much the same on all distros.

So I think the problems you found with NixOS indicate that we must fix
the environment variable collisions.

=C4=9Coja kodado!  :-)
