> 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.
I research for that..
I looked for "kernel command". The only sources I found where this*
and this*. Both doesn't mention "persistent overlay".
*http://fedoraproject.org/wiki/Anaconda/Options
*http://docs.fedoraproject.org/install-guide/f11/en-US/html/ap-admin-options.html
Only for USB-Sticks "persistent overlay" is mentioned.

And I found another guy who asked for the same feature.
