Hi,
Here is a patch which I'm using for years in my production
environment.
I usually changes parameters documented in jail(8) for each jails, but
current rc.d/jail has no feature to pass extra parameters at starting
jails.
I hope this patch will not prevent jamie's recent/next work for
rc.d/jail. I'll commit this if there is no objection.
