It's the latter. Which then makes the FIS update another point of failure. 
All this type of stuff isn't an easy problem to solve, however...

There is an existing solution to this allowing you to reliably revert to a 
previous image, but it's only available as a custom option with the eCosPro 
Developer's Kit. Contact info@ecoscentric.com if you want to find out more 
and the URL in my sig gives more info about the EDK in general (eclipse 
IDE, etc.etc.). Ad over :-).
