USB booting :: why you cannot use swap on usb

the reason is exactly as the last guy stated, swap reads and writes to the swap locations as that is its natures, sort of like a RAM, right? With a limited number of reads and writes in the flash that are used in these USB storage drives, you can burn all of t he reads and writes within a very very small amount of time, so it is best to not use ANY swap at all on a USB pen drive that is comprised of flash memory IC's. I think that shoudl cap it, no?
