and all of its descendants inside an environment with a very limited
ability to affect the system outside that environment, even for
processes with superuser privileges.  It is an extension of, but
far more powerful than, the traditional UNIX chroot(2) system call.

The host's jail rc.d(8) script can be used to start and stop jails
automatically on system boot/shutdown.

In multiple situations the host's jail rc.d(8) script does not check if
a path inside the jail file system structure is a symbolic link before
using the path.  In particular this is the case when writing the
output from the jail start-up to /var/log/console.log and when
mounting and unmounting file systems inside the jail directory
structure.");
