In my opinion, the easiest way to do it is to just create a proper jail (you can always use an aliased IP from RFC 1918). It can be pretty minimal, just the base system and the ports collection (which can easily be rsynced or cpduped from the host environment) and without any packages installed (which greatly simplifies pkg-plist checks, should you perform any). For jail creation, please see jail(8). =Anton. -- Perl is strongly typed, it just has very few types. -- Dan Sugalski
