In general, I don't trust -ef to not have occasional false positives
(for instance, consider the case of NFS to a remote device with a Very
Large filesystem, It's not possible to have a 32-bit
unique-within-filesystem identifier if there are more than 2**32 files
on the box.  NFS will make do as best it can, but will no doubt have
to generate duplicate-appearing inode numbers every now and then).
