Thanks! The first link and the availability of the grub loopback
feature was definitely news to me. I have used grub in the past to boot
custom fedora livecds, though moved to isolinux following the lead of
the official fedora livecds. While grub may have some disadvantages, it
is pretty cool to know that I can use it already to implement a
proof-of-concept of what I described, while waiting for myself or
someone else to implement the same sort of thing in sys/isolinux.
The second link was also good for reference, though I already know the
guts of all the initramfs issues that will be involved.
Thanks also hpa for confirming that the c32 would be the way to go,
should I embark on the task. Most likely I won't find the time in the
near-term future, but maybe someday.
