ntpd -q can make use of the driftfile to set the kernel frequency:

| # ntpd -q -d | grep frequency
| addto_syslog: frequency initialized -1.752 PPM from /var/lib/ntp/ntp.drift

Note that this is plain necessary for the correct operations of ntpd -q.
If the kernel frequency was not initialised, then a slew would not end
right on the zero offset.


Serge.
