Binary package hint: grub
I'm not sure where to send this... this is a patch to add live CDs in /boot to the grub boot menu. I think this patch is important to the Ubuntu community, because it makes it easy to test new Ubuntu versions, and hence report bugs.
To use this patch, put the attached file, called "50_casper" in /etc/grub.d
Then, you can use it to boot of ISO images in /boot as follows:
* save the ISO image in /boot
* run "sudo update-grub"
* the ISO image will now be in your boot menu... you can select it to boot from it.
