Greetings John Dowd,

Hmmm... it looks like your name got truncated, or maybe mine got
extended =:-)}}}

I put FDOM on a large ~300MB partition of the microSD card with the
rootfs in /dev/mmcblk0pr and the kernel in /dev/mmcblk0p4/boot/

In order to get it to boot, I put a soft link at the card's root
pointing to the desired kernel (I have two of them in there at the
moment), thusly:

(as root in where /dev/mmcblk0p? is mounted) # ln -s
boot/long-kernel-name.bin uImage.bin

There are still a bunch of things I need to get correct about booting
from the microSD card, but it does boot from just one partition.

Cheerio!
