Ah, yes.

It was just an idea - yes, you're right, it's not particularily good.

I was just trying to imagine a way that would both save space (so that a 
resource which needs one bit doesn't take four bytes) and is capable of 
storing attributes from many file systems. OTOH, I'm afraid it's impossible 
to create a completely transparent FS interface - that would mean every FS 
has to have the same features implemented or faked. 
What we discuss here is a completely new FS and we can implement/invent 
anything we want. But we have to remember that there are other file systems 
*we will not* be able to modify.
