Agreed, it looks nice.

The nice thing is that we could detect conflicting iptables rules
statically if we wanted to: =E2=80=98guix system reconfigure=E2=80=99 would=
 proceed if
and only if there are no conflicting rules.  I don=E2=80=99t know how diffi=
cult
and how annoying that could be, but it might be worth considering (as
future work=E2=80=A6).

Thanks,
Ludo=E2=80=99.
