How does the availability of local cache storage impact these upgrades?

It seems that it would be trivially easy to store an image of the 
flash memory on the hard disk, and to build the image of an update on 
that disk as well. One might even be able to use the volatile system 
RAM to store a temporary image, although this would be vulnerable to 
a power glitch.
