Ezjail and iocage put the jail configuration in different places. Perhaps
man jail is the answer:
-f conf_file
Use configuration file conf_file instead of the default
/etc/jail.conf.
I've never done this. I've used the jail command, ezjail, and iocage I've
always let the tool choose the location of the jail configuration. Moving
it will mean, at a minimum you will have to rewrite the scripts for:
starting, stoping, and console. You will also have to do something with
/etc/rc.conf. If it were me, I'd let sleeping jail configs lie :)
