Of course, it is great to learn that some tools can do this or that. However, this only is helpful to those who are just choosing what to use for the future. Once your choice is made, you (at least I) kind of avoid jumping over to doing something using different tools, especially what is already done some specific way on your production machine. I guess, what I'm trying to say is: don't be surprised if OP finds your effort to help him ultimately useless. Incidentally, I for one set up jails "by the book", not by using some tool which does it all for me behind the scenes. So, reference to any tools are kind of set me off (hence this my reply ;-) Just my $0.02.
