Clearly / or /etc cannot be shared between GuixSD and another distro;
each distro needs to have full control over these.  My suggestion would
be to share nothing but /home (and /gnu, /var/guix, and /etc/guix if you
want to able to use Guix on the other distro).

I can=E2=80=99t really advise more than this since the specifics are then a
matter of taste.  :-)

Thanks,
