Roll a large tarball (e.g. a complete FreeBSD installation).  Copy it to
different machines with different filesystems.  Untar and run mtree on
the result.  Notice that you get different output on each machine
because they report different sizes for directories; one might report
the actual on-disk size (which might vary depending on past contents)
while the other might report the number of entries.
