| # 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. | |||||
