Traditionally (and even now in most unices) hard links to directories were not allowed, in order to prevent endless recursive cases. Apple added the feature to HFS+ in 10.5 so that Time Machine could make use of the optimization you describe. There are rules about directory hard links so that pathological recursion still cannot happen: http://lists.apple.com/archives/darwin-dev/2007/Dec/msg00029... |
