Description

If you add a trailing dot on the domain name in the "domain name" and "domain search list", this is accepted. The DNS Resolver retrieves this domain name from a lease and adds a dot: the configuration file ends up with 2 trailing dots and unbound fails to parse its config file.

I believe adding the trailing dot in the domain name of the dhcp server is allowed but the DNS resolver should detect this trailing dot and not add a second one.
