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.
