Pulling the thread a bit more, Jan-Piet Mens @
"Alert, backup, whatever on DNS NOTIFY with nsnotifyd"
appears to refer to that same challenge,
"This is a very welcome alternative to doing it in Perl, as I did when I wanted
to be notified of new and changed KSK in a zone."
"Being notified of new and changed KSK in a zone"
& implements a "key-listen.pl" script that listens for & reacts to KSK changes.
From just reading (don't see the source code?), it's triggered by the NOTIFY from NSD and subsequently polls for DNSSKEY RRSet ...
I don't yet know if what specific state transition info is carried in that _NOTIFY_, or it it's sufficient.
