      Been seeing this recently in the DHCP logs:

      Sep 18 16:48:13 dhcpleases Sending HUP signal to dns daemon(37005)

      After every DHCP transaction, it almost seems like DHCP is trying to kill DNS? I do have the option to register DHCP hostnames (dynamic and static) with Unbound, but not sure what warrants the HUP? Anyone have any ideas to enlighten me?

          Definitely the first. I'm registering leases in Unbound. So I suppose this is expected then; once the ACK goes out, the hostname is registered and Unbound is reloaded?

            Yes because Unbound can't otherwise update the host entries to make them available for resolving. It's a common UNIX methodology for services to reload configuration files on SIGHUP and ignore changes otherwise.
