Upgrade 21.1.5 to 21.1.6: DNS registration of DCHP leases not working

[kiwieater]

Hi there,

yesterday evening I upgraded from 21.1.5 to 21.1.6. After the upgrade the DNS registration (using unbound) of DHCP static maps no longer works. I only get NXDOMAIN responses when directly querying OPNSense's unbound using "dig @<opensense-fw> <DHCP-static-map hostname>.<DHCP-static-map domainname>". This always worked just fine before.

In the changelog for 21.1.6 I see that something was changed with the registration of DHCP leases:

  "unbound: use dhcpd_staticmap() for lease registration"

If anyone here happens to be able to provide either

  * information on how to forward-fix this (preferred), or
  * information on which package(s) to downgrade (unbound? dhcpd? both?) as a temporary fix

that help would be greatly appreciated: I am really suffering from this: For instance, I had to hard-code the DB IP into my webmail-config, as DNS resolution of the DB host no longer worked. I use DNS all over the place and expect issues to pop up all over the place 

Best,
KiwiEater
