I've added a file called 'jail' there and /etc/rc.d/jail will then
pick up configuration data from /etc/rc.conf.d/jail.
I think it's quite a useful feature and would support it's
continued existence. However I wonder who else might be interested
in a better referencing method more like a perl hash or YAML files
for the configuration data.
There's a clear nesting behaviour there built from shell variable
names that I find a little bit overextended.
