Terminology
There is always one zone defined, named the "global" zone. Zones hosted by a global zone are known as "non-global zones" but are sometimes just called "zones". The term "local zone" is specifically discouraged, since in this usage "local" is not an antonym of "global". The global zone encompasses all processes running on the system, whether or not these processes are running within a non-global zone. Unless otherwise noted, "zone" will refer to non-global zones in this article.
