DHCP server accepts trailing dot in domain names, DNS resolver adds another and breaks
100%
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.

To be clear: this happened with a static lease.

This is true only for the DHCP static mapping "domain name" or the System / General / Domain, but not for the "domain search list".

The trailing dot is no longer allowed in input on the fields in question which would result in an error.
