Adding ivp6 to a similar jail setup.

        host.hostname = "${name}";
        path = "/usr/jails/${name}";
        allow.raw_sockets = 1;

        mount.fstab = "/etc/fstab.${name}";
        mount.devfs;
        mount.fdescfs;
        mount.procfs;
        allow.mount;
        allow.set_hostname = 1;
        allow.sysvipc = 1;
        #devfs_ruleset = "10";
        #enforce_statfs = 1;
        #allow.mount.devfs = 1;
        vnet;
