# Like our resolv.conf hook script, we store a database of ntp.conf files
# and merge into /etc/ntp.conf
# You can set the env var NTP_CONF to another file like this
# dhcpcd -e NTP_CONF=/usr/pkg/etc/ntpd.conf
# or by adding this to /etc/dhcpcd.enter-hook
# NTP_CONF=/usr/pkg/etc/ntpd.conf
# to use openntpd from pkgsrc instead of the system provided ntp.
