Out of curiosity, why did you settle for a /etc/jail.conf instead of a
/etc/jail.d/? Your config file format introduces the dependency into an
expensive parser while adding little value. Even worse, the user now has
to struggle with just another format describing the system.

I can foresee that my automated jail management tool ezjail will not be
able to support the jail.conf format due to the lack of a parser. A look
into ezjails config directory structure can give you a hint of how to
achieve some similar clean up with built in tools.

I am not saying, the config directory format is perfect, the current
redundancy in jail_JAILNAME variables is a mess, but inventing a
container format where files would do just fine in my opinion is overkill.
