So here is the funny thing. I don't know why this didn't post before but here goes.

I want to save my persistent home currently on my flash drive, to a home on a DVD-RW that actually contains the OS. Is this possible? Has anyone done this before I waste a DVD-RW?

Basically I want to download knoppix, burn the ISO to the DVD-RW, and then later add my knoppix.img to that disc. Does that make sense? Does anyone know how to do this?
