no - we are misunderstanding each other. I understood your report to
say that (for example - there's details missing), at the "/", or in "/homes"
there is a symbolic link
homes -> /homefs/u0
or in /homefs/u0
purslow -> (something).
If "/" is world-writable (not so, but it's not owned by root, I guess)
then someone could modify the link to point elsewhere.
(If my understanding is not correct, I'd like to find out, so we can focus
on what the problem is).
