Yeah. I think that's broken. It gets worse when you start doing other posixy things. Say you do 'mv foo bar:baz' on an ntfs partition. Those strong in the force will recall that rename() is supposed to atomically unlink 'bar:baz'. Instead you seem to be asking it to add an extra stream to 'bar'. So should we still unlink the old 'bar'? And then what if 'foo' is a multi-stream file? Where do the extra streams go? Or do you just get a big fat -EINVAL for every special case?
I think ultimately there is no posixy (or least-surprise) way to deal with such things. If we truly need forks, we need a new api to manipulate them. Cleverness with ':' or '/' only takes you so far.
