I can't answer your question but I am interested to know how you intend
prevent unwanted writes to the SD.
I have installed the live image on a Compact Flash (/dev/sda) card from USB,
also an image that I made using MID2. They both boot OK on my IEI Kino-Atom
board .
I can (re)mount /tmp on RAM OK but the problem comes with /var. There is so
much that it expected to exist in /var that it crashes after a remount to
RAM.
Ideally the whole RFS should exist in RAM which I guess the USB stick does
when you run from it.
