	Keep in mind that NSD is not suitable for use as a 
general-purpose authoritative-only server.  If you're running a TLD 
nameserver, then it's probably okay (although the SUNET folks 
reported lots of problems with it when they tried to use it for 
serving the various ccTLDs for which they are authoritative).

	But it's not okay for use as a general-purpose authoritative-only server.
