Comment 2 for bug 508802

I think CD/DVD boot does not need CD but just hitting "c" at startup should be enough, no?

Regarding the USB boot CD, this can be done too in Puredyne. In fact you just need to pass an extra boot argument from the isolinux prompt when the CD/DVD is booting. Something like "from=/dev/sdb1" (or "live-media=/dev/sdb1") and it will use the USB device as live medium.

If you do not do this, but just boot from the CD/DVD with the key inserted and the default options, the persitence will work and the changes will be recorded on the key, just like usual.
