I'm assuming you are building this on F9?
I wasn't, I was using the script and kickstart in the koan source which was fc8. I've switched to the development branch which is fc9 and re-built it.
The cd image that comes out of that works, as in, it boots and starts executing the scripts. I believe I can modify things to do what we need.
I also tried using the livecd-iso-to-pxe script to convert the iso into a pxe boot kernel/initrd and pxelinux config file. That also worked as far as I could tell booting an actual machine using the generated /tftpboot tree (it generates a kernel, initrd, and pxelinux config file)
However, I tried booting the kernel and initrd with qemu using its -kernel and -initrd options, and it wouldn't work. I'd like to get this to work if possible so I can rapidly try new images without booting up actual hardware.
It's actually not that big of a deal because qemu boots the iso just fine. I'm just curious why it wouldn't boot the kernel/initrd directly. The command line looks like this:
qemu -m 256 -hda ~/disk.qcow2 -kernel vmlinuz0 -initrd initrd0.img -append "root=/koan-live-cd.iso rootfstype=iso9660 rootflags=loop"
It errors with a kernel panic being unable to mount the root filesystem. The append line was copied from the generated pxe config from the livecd-iso-to-pxe script. /koan-live-cd.iso is a file in the initrd.
Anyways, if that's a dead end, I won't worry about it. I'm going to try and modify the koan live cd to be a cloner live cd. I'm first going to get it working with dd, since partimage isn't in the repos and I'll have to build it myself.

Sure. Perhaps you can take a picture of the actual error, so we can run
it by the livecd-tools folks?
