Possible file loss in unusual situation

I've been experimenting with this feature, between disk images (not yet brave enough to try it with whole volumes). It's an excellent program!

One thing I did notice, though, was this: If after you've made the sandbox you change the name of one of the shared directories, either in the original or in the sandbox (so that the names are no longer the same), then 10.4.9 (and I think earlier) systems will maintain the link: that is, your files -within- that directory will still be accessible from the sandbox.

But if you do a smart-restore (as the manual advises), the files and the directory can be deleted. (It's reproducible.)

My -guess- is that SD is trying to decide whether to copy the link/alias/whatever back from the sandbox to the original and, when it detects sharing, will not do so: see the log. This is of course how it should behave.

But when the names no longer match, then it -does- copy the link back over the original :-(

In short, in this (strange) situation, where one has "messed" with the sandbox/original relationship (although perhaps accidentally), the sandbox -looks- ok while you are using it, but after restoring you have lost a directory and all its files.

At that point you must get them from the backup you took before doing the restore ;-)
