 # Sample dhcpcd hook script for NTP
# It will configure either one of NTP, OpenNTP or Chrony (in that order)
# and will default to NTP if no default config is found.

# 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 override the derived default on
# systems with >1 NTP client installed.
# Here is an example for OpenNTP
#   dhcpcd -e NTP_CONF=/usr/pkg/etc/ntpd.conf
# or by adding this to /etc/dhcpcd.conf
#   env 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 Chrony instead, simply change ntpd.conf to chrony.conf in the
# above examples.
