Now this I agree with, in the sense that I think that if we want to support this, it should be supported at a VFS layer. On the other hand, I think doing it inside the filesystem with ugly hacks is an acceptable way to prototype the idea before it's been proven to really be workable. Maybe it has more problems with legacy apps than we'd expect.. Linus
