Thanks much for the info, Jeremy. I ran the mkisofs script as you specified below (we are on an i386 architecture) and re-burned a CD from the newly-created ISO file. On booting, it gets to the point where it says "Booting the kernel.", hangs for a few seconds, then the following appears on the screen:
--------------------------------------
WARNING: Cannot find root file system!
--------------------------------------
Create symlink /dev/root and then exit this shell to continue the boot sequence.
bash-3.2#
Any thoughts? Something obvious I am missing?
Thanks,
Todd

You'll have to run mkisofs with the appropriate options for making the
CD bootable on your arch. On x86, that's something like 'mkisofs -b
isolinux/isolinux.bin -c isolinux/isolinux.cat -no-emul-boot
-boot-info-table -boot-load-size 4 ....'
Alternately, you can also use the --base-on support to build derivative
images
