Describe the bug

Example config:

• DHCPv4 with:

  • Domain name: abc.com
  • Domain search list: google.com

• Unbound DNS with:

  • Register DHCP static mappings checked

All static records will be listed under the "Domain search list" domain instead of "Domain name" domain.

Verified by cat /var/unbound/host_entries.conf and see all my static entries with google.com domain set instead of abc.com domain set. Also verified this happens with dnsmasq set, so the issue is in the DHCP implementation side.

looks like a regression from #4642, fixed in 7ef730a

can you try the following on a console?

opnsense-patch 7ef730ac fixed the issue, tested that the correct file was written after adding back the domain search list in dhcp and restarting both dhcpv4 and unbound.
