This might be true but I don't think this really helps now.  The build
in bootflash: on the Sup32 is only 64MB. (as is on the 720)  You can't
even hold images on that card.  As for the Sup32 specifically, the
sup-bootflash is nothing but an on-board CF card, so I don't see how it
can possibly be any faster than the external one. (unless of course you
use a lower quality external CF card)

Even longer on an upgrade.  By the time all of the FPD are set and
everything syncs up it can be 10min or more... :-(

Don't try to out-weird me, three eyes. I get weirder things than you in
my breakfast cereal.
