I just tried this on Windows XP.  On a FAT32 or a NTFS filesystem the
inode is unchanged.  On a FAT filesystem, it changes.  I assume that
means that FAT doesn't support a real file ID.  The only thing I think
anyone would be using FAT for these days is possibly a boot partition.
That's the only reason I have one.  I use to to multi-boot various
flavors of Windows.  It's the lowest common denominator.

NP.  I complain about this fairly frequently myself.  :-)
