Multiple BIND instances

[Doug Barton]

I'm not sure why this answer has gone off into the weeds, but running 2
instances on the same host is quite simple.

1. Get 2 different (hopefully sets of v4 and v6) IP addresses, one for
each instance.
2. Set up 2 different chroot environments, one for the authoritative and
one for the resolver. Included in this setup will be the appropriate
listen-on arguments in named.conf.
3. Run each instance with the appropriate command line arguments to
chroot into its own environment.
4. Profit.

Adding virtualization makes sense for some services, but it doesn't for
BIND, which has a very intelligent chroot ability.
