tag_insight = "The jail(2) system call allows a system administrator to lock a process
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 device file system, or devfs(5), provides access to kernel's device
namespace in the global file system namespace.  This includes access to
to system devices such as storage devices, kernel and system memory
devices, BPF devices, and serial port devices.  Devfs is is generally
mounted as /dev.  Devfs rulesets allow an administrator to hide
certain device nodes; this is most commonly applied to a devfs mounted
for use inside a jail, in order to make devices inaccessible to
processes within that jail.

Due to insufficient parameter checking of the node type during device
creation, any user can expose hidden device nodes on devfs mounted
file systems within their jail.  Device nodes will be created in the
jail with their normal default access permissions.";
