I am trying to set up a live Ubuntu CD with a custom kernel. To set up the live CD I followed the instructions presented here: https://help.ubuntu.com/community/LiveCDCustomization
For creating my custom kernel, I downloaded the sources from the Ubuntu git repository and I compiled it with my added customization. I then generated the .deb packages and installed them in the chroot environment and copied vmlinuz and the initrd into the casper directory of the liveCD.
The problem that I am having is the live CD no longer boots. It gives me an initramfs shell from which I could not figure out where to go from.
Any help is much appreciated.
