Multiple Named Daemons on one machine

[Kevin Darcy]

Your config file needs to be relative to your chroot dir.

P.S. What's with the double slashes (//) in the explanation blow? And why is your
startup script checking for the existence of the executable twice in a row? Are you
afraid that someone has deleted the executable immediately after the first check?

P.P.S. BIND 9.1.0 is somewhat stale. Consider using something newer.
