It is not at all unlikely that I unintentionally ommited some of these 
important details. :-/

OK, that IS weird, because I can!

[root at sheeva /usr/src/arm/rootfs-f12]# usr/bin/sha512sum /bin/bash

The results are definitely different when using the sha512sum from the 
tar ball.

(/usr/src/arm/rootfs-f12 is a fresh, pristine tarball extract)

Where are our methods diverging?
