This assumption is apparently only made in chroot situations but is wrong, regardless. On top of that, it's quite common to specify driftfile, if not also pidfile, in one's ntp.conf. This apparently overrides whatever is given on the command line, but I don't know if it's safe to assume that it always will. The fact that the default driftfile and pidfile locations are confusing was raised a couple years ago: http://lists.freebsd.org/pipermail/freebsd-questions/2005-May/087170.html >How-To-Repeat: >Fix: Ideally, stop using the default driftfile name "ntpd.drift"; change ntpd_flags to refer to ntp.drift. Alternatively, leave the default driftfile as "ntpd.drift"; change /etc/rc.d/ntpd to refer to ${name}.drift (perhaps) instead of ntp.drift. In either case, update the FILES section of the ntpd(8) man page to refer to the actual default. Note that /etc/rc.d/ntpd still won't really be very smart about its symlinking of the driftfile, since it could be overridden by ntpd_flags or within the $ntpd_config file, so consider making that more robust, or at least display a warning if the file isn't where it was assumed to be. >Release-Note: >Audit-Trail: >Unformatted:
