I am not aware of any such feature or attribute which policy could check so I think all you can do is run policy to find the symbolic links and then check each link to see if it points into the same file system. You might find the mmfind command useful for this purpose. I expect it would eliminate the need to create a policy to find the symbolic links.</div>
