So, find is given the -xdev option. It stats all the files, and checks
to see wether the files are still on the same mountpoint as the
directories on the commandline.

So, tar is packing an archive, and it wants to detect hardlinks to
files that already are in the archive. To do this, it makes a list of
<devno, inum, filename> triplets for the files that it's already put
into the archive.

Richard, please explain to me why this is going to work on a libc5
based system?

Roger.
