Re: Make bootable CDROM.

You can simply tell the kernel to mount the root read-only. Just create /tmp and /var ramdisks (tmpfs). It's also a good idea to extract the /etc on ramdisk too (form a "factory" archive located on the read-only partition). On most boards that I develop the root is cramfs (read-only) and contains only stuff that should not be chaged by the end-user/client.
