The drift file is an optimisation.  ntpd should work without it, but 
will take longer to acquire lock after a restart.

What would cause more problems would be a drift file that was present, 
but read-only, as ntpd would skip its frequency calibration and trust 
the frozen value in that file, then suffer wild swings as it begins to 
discover the value was wildly wrong.
