Huh? I'm not confused about chroot() vs. FreeBSD's "jail(2)". Are you?

When I say "chroot jail" I mean an environment that's been specifically
designed as a ``jail'' to try to contain an untrusted process. It's
different from a plain call to chroot(2) which may, or may not, create a
suitable environment to be used as a ``jail''.
What gets complex is when you discuss a jail(2) gaol in FreeBSD circles
though.... :-)
