Jails are their own userlands, so you would check them as you would the host,
but from within their environment. If you set up Poudriere, you can have your
own repo that you update as you see fit, compile with the options you want, and
simply have the jails install everything from it, automatically updating in a
cron job. This is especially useful if you have many jails (or many other real
machines) and not terribly difficult or complicated if they can all use the
same packages (i.e., you don't need different versions of the same package for
different jails).
