On most of my systems, I solve this by generating /etc/hosts from the
host's primary (from ohai's point of view, that is, the one that will be
picked for traffic sent to the default route) legacy IP address and IPv6
address.

There are of course many ways to skin the cat, this is just mine.  (And
it gives me best of both worlds.)
