[PATCH] unbound-dhcp-leases-bridge: Fall back to the default domain

[Michael Tremer <michael.tremer@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 1079 bytes --]

When the bridge cannot detect a domain name for any of the leases, it
uses localdomain which is not always the best choice. So instead, this
patches changes the behaviour that we read the default domain of the
firewall.
