you have to show how it actually does matter. when you deploy a board and programming the flash directly, you don't let the regions grow arbitrarily. you know how big the space for u-boot, or the kernel, or dedicated config space, or anything else is going to be. if you want to arbitrarily append things, then you're going to use a filesystem. -mike
