Thinking about it, what do you think is the risk of using AF_INET6
unconditionally?

AFAICS it just works.  Is there a switch somewhere that might affect
that behavior?

(I still think that changing ‘make-inetd-constructor’ to accept multiple
addresses is a better fix longer-term, but if we can have this quick
fix, that’s great.)
