Such config changes are made by scripts in the dhcp client configuration, which you can modify
as you wish. Of course check what files are overwritten on package upgrades and see what countermeasures
you need to take.

These devices will also pull the NTP server list from the DHCP server if the DHCP server provides. Overall this works. The DHCP client appends the additional NTP servers to chrony.conf as expected. However, from my understanding chrony will then use any of the NTP servers listed in chrony.conf. I have a customer request that chrony would use only the NTP servers provided by the DCHP client. I'm trying to figure out what my options are to make this happen.

For example, chrony.conf is the base configuration, then tell it to use either chrony_defaultservers.conf or chrony_dhcpservers.conf? Or does someone have any other methods that they have implemented that I haven't considered?
