-DNSSEC needs time, time needs ntp, or power off RTC
-Many consumer routers are cost thrifted without RTC
-Conf "val-override-date: -1" disables time inside DNSSEC
-Need restart as option is not dynamically switchable
-hotplug/ntp is used to set file /var/lib/unbound/unbound.time
-UCI will add or remove option depending on flag-like-file

-Detach from old interfaces cleanly
