A jail is a chroot'd environment whereby the processes running with it are
restricted in what resources (primarily files/directories, but also sockets
and such) they will be able to see.  Anything outside of the virtual root of
the jail is not only inaccessable, but won't even appear to exist to
processes running inside the jail.  Examples you'll probably recognize are
the "sandbox" people often run BIND in, or the FTP anonymous root directory.
