Right, unionfs should be well suited for this. Then you need at least three filesystem processes: The cd-rom, a ramdisk (tmpfs or some ext2 on an image), and the unionfs. Which should be the root filesystem? The ramdisk as root seems easiest, but needs some hacking to get the image through the boot process to the ramdisk server. unionfs as root seems a little hairy. The cd as root filesystem could also work, either with passive unionfs and tmpfs translator settings on well chosen nodes on disk, or with a startup script that installs active translators. Does it work to install active and/or passive translators, in particular unionfs, on / ? /Niels
