I have done this, in /etc/default/ntp.

I created, by touching, both of the potential filenames at the path 
specified in /etc/default/ntp, but discovered just now that I sill own 
them, so chowned them to ntp:ntp just now.  Likewise the parent "ntp" 
directory in /usr/local/lib.

Now we wait...

Thanks, C de-Avillez, this is stuff that simply is not important enough to 
make the man page.  And yet its quite important to verifying that it is 
indeed working.

Cheers & Have a merry Christmas, Gene Heskett
