It is true, that the jail-id is the only unique identifier from OS or developer view. But there is another view, the administrators view: The jail-id is a not predictable number, but the hostname is in many (most?) cases the unique reference. So it makes sense to be able to select a jail by it's name. The rc.conf jail framework also requires unique hostnames for jails, because the jail-ids are write to /var/run. So I agree that the man page should contain the warning, that the selection by hostname/ip address may lead to ambiguities, but this is a very useful feature in daily jail administration. -- Frank Behrens, Osterwieck, Germany PGP-key 0x5B7C47ED on public servers available.
