While opening two separate sockets is cleaner and is the maximally
portable solution, there was a long discussion about this on debian-devel
a while back (when the bind.ipv6_only setting to 1 was temporarily added
in unstable), and the conclusion was that Debian should default to 0
because that's what the IPv6 standards expected and too much software
assumes that default behavior.

People who have the setting of 1 probably got that configuration file
introduced during the time period when this was the default in unstable.
Debian never released with that setting.
