Hi

On all of my pcs I've hardcoded /etc/rc.d/ntpd to point to
/usr/local/bin which is where ntp-dev-4.2.7p465 ended up.

All four ntp.pool.org servers have:

rc.conf:
ntpdate=YES
ntpd=YES
ntpd_flags="-g -N -p /var/run/ntpd.pid"

Probably one of /etc/rc.local, /etc/rc.conf.local or 
/etc/rc.local would be correct place but my netbsd systems
date from 1997 and have a lot of files I'd like to get rid
of I but don't unless I have a problem as the diskspace 
used is insignificant.
