pkg(5), the image packaging system, is an attempt to design and implement a
software delivery system with interaction with a network repository as its
primary design goal. Other key ideas are: safe execution for zones and other
installation contexts, use of ZFS for efficiency and rollback, preventing the
introduction of incorrect or incomplete packages, and efficient use of
bandwidth.
