Nod.

Fwiw, I don't really care which way it gets fixed - we'd need someone
to decide which is the "right" setup so we can refer people to that
when they complain about services (not) listening on ::1.

Given that DNS seems to tend to resolve localhost to both 127.0.0.1
and ::1, I guess the proper solution would be to put the same in to
/etc/hosts.

Re wheezy, as we are shipping both versions, there's not a real
argument against changing one of them to match the other one. (Except
maybe that the netcfg one is triggered more often.)

How that relates to net.ipv6.bindv6only is then another interesting
question...
