The problem is the current mechanism _forces_ the user to have different environments on the same box - there's no choice. Which is, as Al says, just like environment variables. But not like files - if I create a file called $HOME/foo, I expect that I can access it from a different login. I might want to have different environments, but that's not the _default_ when dealing with files. The question is whether private user-mounts should, by default, behave more like environment variables or more like files. -- Jamie
