Update: I tried to create an ISO today with the new kernel (vmlinuz) from Joseph's packages at casper/vmlinuz. No other changes to the ISO at all. It boots that new kernel... to an initramfs prompt saying it can't find the live filesystem. Ugh. I suspect that issue relates to needing to also update casper/initrd.lz filesystem to match the kernel. I'm in the process of attempting that, but I am running out of time, I have other committments this evening and basically all day Sunday. I'll do my best, but it's not looking good at this point for a working test ISO this weekend from me. If anyone else "out there" is also working on creating a test ISO with Joseph's kernel in it, PLEASE say so, so we can avoid duplicated work, and so I can relax a little! My current script (that fails as described above, perhaps because it does not update the initrd.lz) is attached, in case it is useful to anyone. Jonathan
