It verifies that the device number and inode of the parent directory once it's returned to it in an upward direction are the same as the saved copy of that information when find initially left that directory moving downward. GNU find has had this feature for years. In fact, find has to take special steps up update the parent-directory information when it has found that automount mounted that directory as find moved downward. That last feature is new in GNU find 4.2.8. Regards, James.
