This is basic, though. If the stuff was stored in a Unix filesystem it would be the difference between a symlink (correct strategy) and a hard link (risky). Correctly implementing the hard link strategy (in the Unix analogy, this happens in the filesystem code itself) requires reference counting. Either you invest the time to implement that, or you should stick to symlinks.
