The live CD systems that I've dealt with have all created a minimal, in-RAM /
(or root) using ramfs. Just boot with your favorite live CD distro, open a
terminal and run mount. It does mean that the image of / can be read-only and
it takes surprisingly little RAM to have the bits of Linux in RAM that are
actually volatile.
