Subject: dhcpd 4.4 named ddns and additional event triggers

Hi folks, I'm using dhcp 4.4.1 with named ddns updating.
I'm researching performing additional triggers using event interface.
Older man pages state I cannot configure event statements if I'm using
internal ddns mechanism, however the man page for 4.4.1 just gives a terse
description of events, and makes no mention whatsoever of whether event
statements can be used in conjunction
with internal ddns mechanism:
REFERENCE: EVENTS
There are three kinds of events that can happen regarding a lease,
and it is possible to declare statements that occur when any of
these events happen. These events are the commit event, when the server
has made a commitment of a certain lease to a client, the
release event, when the client has released the server from its
commitment, and the expiry event, when the commitment expires.
To declare a set of statements to execute when an event happens, you
must use the on state-ment, followed by the name of the event,
followed by a series of statements to execute when the event happens,
enclosed in braces.
Is it now possible to configure event declarations and still use internal
ddns updating?
Thanks

I've been using "on commit" along with DNS updating for years:
on commit {
??? log (
??? ??? info,
??? ??? concat (
??? ??? ??? "Host:", pick-first-value(option fqdn.hostname, option host-name,
"(none)"), "=>", pick-first-value(config-option
server.ddns-hostname, "(none)")
??? ??? ??? ,"? VendorId:", pick-first-value(option vendor-class-identifier,
"(none)")
.
.
.
??? ??? )
??? );
}
What is it that you want to do?
