Jail.conf is one of the targets for my command line tool to interface
with libUCL (the library for parsing and manipulating structured
configs, already used by pkg). The jail.conf format will likely need to
be tweaked a bit to make it compatible.

My main reason for wanting to do this, is that the current jail.conf can
not easily be programmatically edited by tools like puppet. That is why
I use ezjail, in addition to its existing interface, its rc.conf style
means I can edit an ezjail config with the sysrc tool included in base.

ezjail would not lose its value even if the base jail tools were very
easy to use. EZJail has features, like the 'basejail', that the base
tool is never going to have. Not everyone needs that feature, but I like it.

EZJail is not going away.
