[conspire] missing rDNS for (intentionally missing) IPv6

Quoting Nick Moffitt (nick at zork.net):

Roger that.  I'll spare everyone my rant (peppered with theological and
biological references) about unexpected automagical networking.  Suffice
to say, I consider wholly admirable Debian's network config files from
which you can picture the ifconfig and route (old school) or ip addr and
ip route (new school) incantations resulted during boot, based on them.

And, basically, if I'd _wanted_ automagic networking, I'd have enabled it.
Or so I naively thought.

This thing makes me think the Frankenstein story's villagers making
reflexive recourse to pitchforks and torches was also an excellent model
for response to whichever wise guy thought "I know!  Let's make IPv6
autoconfiguring by default.  What could possibly go wrong?"
