Vnet requires you to use the new -c syntax to create jails rather then the  
old syntax currently in use by rc.d/jail. I have a half done patch to make  
rc.d/jail use the new syntax and some other stuff which I intend to finish  
after my exams this week. I looked if I could quickly distill something  
useful from the changes I was testing, but that didn't pan out. You could  
try using "-c vnet" in flags, but I don't think it'll work (since I don't  
think you can combine the new and the old syntax). As a last resort you  
could jury rig the jail call in rc.d/jail to use the new syntax (line  
638-ish in 8.0-R-p1), how much work that is depends on whether you need  
IPv6, etc. and whether you want ALL jails to use vnet or not.
