Multiple boot environments is a feature originally created by Solaris. It allows you to create a BE, which is a bootable, point-in-time snapshot of the ZFS filesystem. By booting into a snapshot, you return to that point in time in the filesystem. For example, you could create a BE before upgrading, allowing you to boot either into the newly upgraded system or into the snapshot of the system before it was upgraded. Alternately, you could create a snapshot before installing and configuring some software that you wish to test. Once your test is finished, you could boot into what the system looked like before the test.

(Sorry for the inconvenience)

Beginning with version 9.1, PC-BSD supports multiple boot environments on systems that were formatted with ZFS during installation. In 9.1, this feature is configured from the command line. Version 9.2 will provide a graphical interface for managing boot environments (BEs).
