--- Comment #1 from Jamie Gritton <***@FreeBSD.org> ---
The program is correct, and the problem is just in the usage message (also in
the man page). The "old-style" command line is four fixed arguments, with the
non-optional IP address being one of them. You can specify '' as the IP
address, but there has to be an argument.

By the way, that will make a jail with no internet access at all; to make one
without IP address restrictions, you'll need something like :

jail -c path=/disk/jail host.hostname=testjail ip4=inherit command=/etc/rc
