os.rename() raises OSError with a misleading message saying "cross-device" when no cross-device activity is involved.  

Here, running on Ubuntu 16.04.1 using and ext4 filesystem, both filepaths are in the same filesystem, and the error is evidently due to the fact that a file already exists at the target path:

(Pdb) os.path.isfile( '/persist/nobackup/backupDisks/d38BasLijPupBak/d38-backup.20161020/d38-_,.,_home2_,.,_rack/.Xauthority')
True
(Pdb) os.path.isfile( '/persist/nobackup/backupDisks/d38BasLijPupBak/d38-20161020/home2/rack/.Xauthority')
True
(Pdb) os.rename( '/persist/nobackup/backupDisks/d38BasLijPupBak/d38-backup.20161020/d38-_,.,_home2_,.,_rack/.Xauthority', '/persist/nobackup/backupDisks/d38BasLijPupBak/d38-20161020/home2/rack/.Xauthor\
ity')
*** OSError: [Errno 18] Invalid cross-device link: '/persist/nobackup/backupDisks/d38BasLijPupBak/d38-backup.20161020/d38-_,.,_home2_,.,_rack/.Xauthority' -> '/persist/nobackup/backupDisks/d38BasLijPup\
