Thanks for pointing me to the README.Debian comment.  Sorry for not  
being thorough before I submitted this bugreport!

Just to be sure I've got this straight, is it that case that:

1) The recommended way to over-ride the NTP servers offered by dhcp  
is to manually edit the /etc/dhcp3/dhclient.conf file.

2) There is no configuration option available at debian-installer  
time or later via dpkg-reconfigure to turn it off.

Have I got it right?

Thanks!

Rick
