Ok, I'd just like to point out -- if there are any newbies looking at this thread, if you have 50k or even less, that is PLENTY for the rootfs as I understand it. Don't mess around with this unless you think it's fun, or like me, you don't mind reflashing once in awhile. In my opinion, once you start moving files around like this you are risking various problems that you might not even understand well.
