Description

When switching to Kea from ISC and dhcp lease registration is enabled the existing lease file (/var/unbound/dhcpleases_entries.conf) is not cleared.

Since the dhcpleases process is stopped that file is never updated but Unbound continues to reference it causing bad hostname resolution.

This was solved by removing the reference to the old leases file from unbound.conf.

After switching to Kea from ISC the file is still present and populated but devices in it can no longer be resolved. Only new leases in the new files are resolvable.
