A Jail in FreeBSD-speak is one or more tasks with the same kernel Jail-ID, bound on zero or more IP addresses, having the same chroot-environment. One usecase of the FreeBSD Jail Subsystem is to provide virtual FreeBSD-systems within a Host-system. ezjail is about making this as easy as possible, aiming for minimum system resource usage.
