Ha! Found the little beastie from the init.d script. Hehe ;^) I'm smarter than this computer ;^)
/etc/init.d/ntpd start calls a script /usr/local/etc/emulab/ntpstart that has a variable
my $useold = 1;
change it to zero and the beast doesn't overwrite anymore ;^)
Now if only I could get the NTP server to actually work properly, then I will be in business ;^)
