One interesting thing I've noticed is that CCO Software Center says
that the minimum flash requirement is 128 MB but the image I'm looking
at is only about 32 MB. Why is the minimum requirement so much higher
than the size of the image? This is especially strange since the Sup2
can't have more than 64MB of flash on a card.

My plan is to recommend purchasing a 64 MB flash card for each
supervisor module. I can't abide by the minimum requirement because no
one makes 128 MB flash for a Sup2.
