If you're concerned about memory usage - why untar the whole of your root filesystem into a ramfs? My preferred solution is to just mount the root filesystem directly from the flash as cramfs (or JFFS2), with symlinks into a ramfs for appropriate parts like /tmp and /var.
I suppose the best option is actually to union-mount the ramfs over the root, rather than mucking about with symlinks. I just haven't got round to doing that yet.
