Hello Jeff, thank you for your answer.. well the sinple answer why I need it is because my iPlanet installation does fail when trying to install it in a zone that is not global, aparently it does try to install something in /usr directory which is read only and installation does fail on that...

There are several possible solutions which may help you with your goal.
In order to choose from among them, though, we need to know why you would want to make /usr read-write from the zone. Simply making it a read-write mount would violate the security model of sparse-root zones.

in http://docs.sun.com/app/docs/doc/817-1592/6mhahuoo6?a=view document there is something like this:

This resource should not be configured in a whole root zone.

In a sparse root zone, the inherit-pkg-dir resource is used to represent directories that contain packaged software that a non-global zone shares with the global zone.

The contents of software packages transferred into the inherit-pkg-dir directory are inherited in read-only mode by the non-global zone. The zone's packaging database is updated to reflect the packages. These resources cannot be modified or removed after the zone has been installed using zoneadm.

-------------------------------------------------------------------------------- Note Four default inherit-pkg-dir resources are included in the configuration. These directory resources indicate which directories should have their associated packages inherited from the global zone. The resources are implemented through a read-only loopback file system mount.


It does make those file systems as read-only loopback, is there any way to make /usr read/write loopback or even if I need to make it as a separate file system partition of directory. I would like to make it so its read/write partition.

Please help.
