No.  rc.d/jail shall not be extended anymore; please see the framework Jamie posted
on freebsd-jail last year and test/review/report back there.

See http://lists.freebsd.org/pipermail/freebsd-jail/2011-July/thread.html#1568

You get a config file etc and get rid of all the shell "magic" and "nightmare".
