I tested this on the local mirror (which is actually an i386 machine
running Potato), and Phil is right. If you want du to follow symlinks in
the tree, you need the '-l' switch; if you want du to follow symlinks
specified on the command line as their real locations, you need the '-D'
switch. So I got this to work very easily just by using
du -lsDm ${MIRROR}/dists/${CODENAME}/main/disks-${ARCH}/current/
This is really not a big deal as long as you get all the switches right.
