PC-BSD features the “Ports Jail”. In this video you will learn how to use it to install apps isolated from your system.


More information on Ports Jail and how to use it, can be found on the PC-BSD Wiki.

The FreeBSD Wiki has a helpful section on Jails too: FreeBSD Jails. The FreeBSD jail is mechanism implementing an operating system-level virtualisation that allows administrators to partition a FreeBSD-based computer system into several independent mini-systems called jails.
