It's because when you have several users sharing a prefix directory
you'll most likely run into trouble. In particular it catches people
running as root inside a user's dir, which breaks things. If you are
sure that you have taken care of all the potential trouble, you can work
around the check by creating a prefix dir for each user and symlinking
things inside it to a central place.
