Did you run =E2=80=9Cguix system init config.scm /=E2=80=9D?

That=E2=80=99s how I did my first GuixSD install long ago, so I had a safet=
y net
since the other distro was still around.

However, in practice, each distro will want to fiddle with /etc, so it
is inconvenient at best to switch distros if they share the same root
file system.

Good question!  I=E2=80=99m not sure I fully understand your hack but I=E2=
=80=99d like
to read more about it.  :-)
