Debian 12 Cloud image -> Search domain missing

[cr4ckDe]

Has anyone tried using debian 12 cloud image with an opnsense DHCP (ISC-DHCP) server?

I've got one major issue:

The VM can't get my search domain. In resolve.conf the serch domain is listed as "." . The gateway is applied correctly.

Has anyone faced the same issue?

Old question, but maybe an answer:
I'd guess that your DHCP client is not requesting option 119 (domain-search) in it's Parameter Request List.
RFC 2131 Dynamic Host Configuration Protocol:

Under RFC 2131, the server should not return ordinary configuration options that were absent from the client’s Parameter Request List.

Add it manually to your DHCP client config, and if the server has option 119, it should send it now.
