Since then I've heard that it can be done on jail command line, though I never tried as I kind of prefer all my stuff done "generic" and uniform way, something done on command line what does not work in central configuration files be it /etc/rc.conf or /etc/jail.conf feels like hack to me, so I tend to avoid it.
