I don't see it functioning: 3 years 6 months ago and it was shortly afterwards removed again as = neither a) the hostname not b) the ip addresses needed to be unique anymore with multi-IP jails (a) not even before that). The suggested replacement was -n to name the jails yourself. I think the uniqueness limit has since = been removed on that as well but the option has stayed and by default is the jail ID these days and it's name=3D<..> in the modern syntax. /bz --=20 Bjoern A.
