I appreciate the brief customizing Linux tutorial but I'll be lucky to get
enough time on a connected system that will allow me even to just download a new
Kdenlive to a bigger USB so I can burn a CD or DVD from KDenlive.

I still don't know how big to make the root partition bigger on say a 16Gig USB
device or where to change that parameter.

Also, I've ordered a USB case for my hard drives so maybe someday I can just
install to the USB HD from a borrowed Internet connection that will allow it.
