Short version:
Can a jail be given a hostname equal to a DNS CNAME entry pointing to the host?
Long version:
Imagine you have a machine (say somehost.example.net) that provides one or more services to the outside world (just for kicks, let's say NTP and Gopher) and that you therefore have the following entries in the DNS records for your domain:
Now, if you wish to run these services in jails (with IPv4 addresses in the 192.168.0.0/16 range and the host running a firewall to connect the jails to the outside world), can the jails be given the hostnames ntp.example.net and gopher.example.net, or will that cause conflicts with the CNAME records in your DNS, which after all point to somehost.example.net?
