Anybody who runs a "packaged" configuration deserves whatever happens to
him. Windows comes configured to use time.windows.com. AFAIK that's
operated by Microsoft and it's not a problem. RedHat comes
preconfigured to use servers provided by RedHat. That's not a problem
either. Neither Microsoft nor RedHat can, or does, guarantee that the
canned configuration will work well for you!
Further, the NTP developers/packagers/whatever have no idea where you
will be running your system or what your requirements will be. A
configuration that's perfect for a system in Dover, Delaware, will be
garbage if used in a system in Tokyo! Any canned configuration should be
treated as an example. The ultimate user needs to pick his own servers,
his own security, his own locations for log files, etc, etc.
If you need a configuration you can depend on, you have a responsibility
to think about the problem and develop a configuration that meets *your*
I believe that the developers have met their responsibility by providing
documentation that tells you how to "roll your own" configuration.
