Tar uses inode numbers to detect whether it has already archived
a file, and to ensure that when you untar the files again they
are still hardlinked together.

In general, looking at the device number and inode number has
always been the canonical way under Unix to tell whether two
filenames were references to the same file. Messing with that
is going to cause problems.
