Can a system WPAR have a different root file system than the LPAR it is on?

The WPAR MUST have a different root file system to the global AIX root file system. This is not optional. In the global AIX this is mounted at /wpars// by default. This file system contains, for example, the /etc files which must be unique to the WPAR – this forces the fact that each WPAR has its own root file system for its own files. Only /usr and /opt out of the global AIX file systems directories are normally shared read-only; other less critical file systems such as /home and /tmp can be shared too for read-only or read-write access.
