Important notices

Before you add a new report, we ask you kindly to acknowledge the following:

• [x] I have read the contributing guide lines at https://github.com/opnsense/core/blob/master/CONTRIBUTING.md
• [x] I am convinced that my issue is new after having checked both open and closed issues at https://github.com/opnsense/core/issues?q=is%3Aissue

Describe the bug

New registered DHCP names are not registered inside the DNS (Unbound) even though so "Register ISC DHCP4 Leases" is enabled.

I think the issue is there since 24.1 but not 100%. At least I can say it since 24.1.3.

To Reproduce

Steps to reproduce the behavior:

1. Register new hostname through DHCP
2. Request the IP via hostname from DNS -> no response
3. Reload Unbound server
4. Request the IP via hostname from DNS -> working

Expected behavior

Hostname should be registered automatically in the Unbound DNS.

Describe alternatives you considered

Restart of Unbound.

Software version used and hardware type if relevant, e.g.:

OPNsense 24.1.5_3 (amd64). Intel(R) Xeon(R) Silver 4214R CPU @ 2.40GHz (12 cores, 24 threads)

[fob2024]

Exact same behaviour here for OPNsense 24.7.1. Additionally, we have observed that entering DHCP leases still works shortly after restarting unbound.
