Funny that you should ask, I am working on this right now...

The route is most likely a combination of mkisofs, with the (ElTorito) bootable cd-rom extensions turned on (-b), and then a simple cdrecord session. The / filesystem should be first be prepared of it's own. You can see this tehnique in the sample cdrecord command line a couple of paragraphs below, I assume the the Cdrom filesystem-to-be in mounted under 'FD10-000331' My interest in this was sparked a few weeks ago when I read about the NIC (aka ThinkNIC or New Internet Computer) which runs a Linux OS from a CD-rom, using a 4MB flash ROM for /tmp /var and a few other things. I wanted a version of Linux that would do the same, but use a small (40MB max) HD (or compact flash card) as it's /tmp and /var. The NIC OS is freely available, but it's kernel will not boot on generic hardware, it must be NIC hardware. Here is a link to the NIC OS ISO image: http://www.thinknic.com/about/gpl.html On the bottom of the page they list the mkisofs command that they are using to build their bootable / runnable image. Thanks, guys: mkisofs -b boot/boot.img.hda -c boot.cat -A 'NIC' -l -L -N -o /home/nc/image.raw -P MA -p 00-03-31 -R -V FD10-000331 -v Next, I was put onto a unique distribution called DemoLinux, which (supposedly) does all of this as well, thus I don't need to reinvent the wheel. I downloaded the DemoLinux ISO, but the resultant CDrom is unbootable... I used 'cdrecord dev=0,0,0 speed=2 -v -eject demolinux.iso' which has never failed to produce a bootable disk in the past. Weird.
