Ntpd.conf updates from dhcp-options

Using OpenBSD as a dhcp client on a network....curious if anyone has prior
art updating ntpd.conf with NTP server details (ie,
https://man.openbsd.org/man5/dhcp-options.5#option~57) as provided by the
dhcp server.

Looks like there isn't support for "include ..." in ntpd.conf, nor forcing
ntpd to reload config (via sighup, etc)

So, I'm thinking of generating a new ntpd.conf, and restarting ntpd when a
new lease is acquired.

Anyone else solve this?
