Creating a writable directory under a shared directory
You can create a writable directory beneath a shared directory using a symbolic link from the global environment.
If you are customizing software within a system WPAR, it might be useful or necessary to have a writable directory beneath a directory shared from the global environment. For example, it is common for open source software to install into a /usr/local directory hierarchy by default. In order to accommodate an unshared, writable /usr/local directory hierarchy, the global environment administrator must create a writable /usr/local directory. Create a file system called /wpars/wparname/usr/local with the type=wparname option.
