Already possible I believe. I think there's a persistent overlay kernel
command argument that you can point to use a file on your USB drive if
you're booting from CD. I may be wrong on this though.

It's easier just to boot from USB though. Faster all the way around.
CD/DVDs take ages to boot. I know persistant overlay works swell with
this method. I use it personally. Is booting from USB not an option for you?
