Here's YACUZ (Yet Another Creative Use of Zones):
Doug Scott documented a method of building a zone which will never be patched
from the global zone. In other words, when a patch is applied to the global
zone, it will not be applied to a zone built using this method, even if the
patch is for a package which is marked "ALLZONES=true."
Note that this method would not be supported by Sun for the following reasons:
1) It uses functionality which is not yet supported by Sun (Branded Zones).
2) It requires you to edit system files which you shouldn't edit; the syntax
of those files can change.
3) Eventually, a patch will modify the kernel and libc (or other
kernel-dependent libs) in such a way that they will be incompatible with the
'cbe' brand. At that point the zone may no longer work until the 'cbe' brand
is modified.
However, if those doesn't bother you, or if you want to learn more about how
zones *really* work, take a look:
