Bug#301992: DHCP-DNS: displays errors it should ignore

[Brian White <bcwhite@precidia.com>]

Package: dhcp-dns
Version: 0.50-3.2

If a hostname has already been removed from the dynamic DNS server when 
dhcp-dns goes to do it's update, it gets an NXDOMAIN reply.  This isn't 
a problem as the desired results already exist, but a message goes to 
STDERR and the cron daemon mails it.

update failed: NXDOMAIN
update failed: NXDOMAIN

    It seems that anything people have learned prior to puberty takes 
on the
  status of an immutable truth (this is something well understood by 
parents,
    governments, and religions). Rational explanations of why some previous
    belief might be incompatible with the behavior of nature, and a careful
       explanation of the actual behavior of nature are of little avail.
