If a user begins with a single full disk for their entire filesystem, uses tar to backup, and then later adds a second disk, copies everything from /usr and /home onto partitions there (making sure to preserve all interesting bits like ctime/mtime), and mounts them over the original directories, tar should not decide that every file in /usr and /home was deleted and recreated.
