Do you have any info as to how to make those demo CDs? I remember SuSE has a downable demo CD. But how to make one in Red Hat?
There are a couple approaches to take. One is to get it small enough that at least the root filesystem can be loaded in a ramdisk, then the CD mounted on /mnt and other filesystems get loopback mounted (/var, /usr, /home, etc [but not /etc ;)]), then you mount more ramdisks on top of this in places that need to be read-write. It's ugly, but it works and wont' break anything as you have read-write filesystems.
The other option is to modify the system to tolerate readonly filesystems. This isn't exactly easy to do, and you'll almost always have a few places mounted on ramdisks (tmpfs) anyway to run any major apps, but it has a smaller memory footprint and isn't as complicated.
Remember, you can burn any filesystem onto a CD-ROM. You're not limited to iso9660. This means you can have a full ext2 filesystem (for example) on the CD, not having to sacrifice attributes for CD compatiblity (though Rock-Ridge is pretty good, it doesn't have everything).
