This is the approach that I've taken. Works fairly well. You will need to: - Create your own init script (look in: meta/recipes-core/initrdscripts/files as a starting point) - Patch your kernel with AUFS/unionfs/overlayfs if you want something that is not 100% volatile. - Create an "install/update" script that actually takes care of updating your squashfs rootfs from the initramfs.
