Expanding swap as you described it is more work though, and it is easy
to add a second swap partition if more swap is required.  If p2 and p4
were swap, you could still even delete p4 and expand the zpool, and
possibly recreate a new p4 for swap.  I suspect it will be more common
that people will want to expand their zpool rather than swap, so if that
is true, p2=swap and p3=zpool will require the least effort to repartition.
