Package Operations Possible in the Global Zone

If the package is not currently installed in the global zone and not currently installed in any non-global zone, the package can be installed:

• Only in the global zone, if SUNW_PKG_ALLZONES=false

• In the current (global) zone only, if SUNW_PKG_THISZONE=true

• In the global zone and all non-global zones

If the package is currently installed in the global zone only:

• The package can be installed in all non-global zones.

• The package can be removed from the global zone.

If a package is currently installed in the global zone and currently installed in only a subset of the non-global zones:

• SUNW_PKG_ALLZONES must be set to false.

• The package can be installed in all non-global zones. Existing instances in any non-global zone are updated to the revision being installed.

• The package can be removed from the global zone.

• The package can be removed from the global zone and from all non-global zones.

If a package is currently installed in the global zone and currently installed in all non-global zones, the package can be removed from the global zone and from all non-global zones.

These rules ensure the following:

• Packages installed in the global zone are either installed in the global zone only, or installed in the global zone and all non-global zones.

• Packages installed in the global zone and also installed in any non-global zone are the same across all zones.
