[Cbe-oss-dev] Booting from USB

Goal: I'd like to have more than one Other OS available to boot on the
PS3 for testing and demonstration purposes.
Restriction: Only 10GiB are available to allocate.
Proposed solution: Be able to boot from removable USB sticks 8GiB in size
Progress: I have a great working installation of Fedora 10 currently. I
copied all of the files from /dev/ps3da1 to /dev/sda1, and updated the
/etc/yaboot.conf on /dev/sda1 to reflect root=/dev/sda1 and boot device
/dev/sda. When I ran ybin (even though I was chrooted to a /dev/sda1
root, it still gave an error of no such device /dev/sda, and it did not
appear to update the /boot/yaboot/yaboot.conf. I have tried to boot this
with petitboot and kboot with no success. The fatal error is:

Unable to access resume device (UUID=blahblahblah)
mount: error mounting /dev/root as ext3: No such file or directory

I suspect something is wrong with the yaboot binary image or the initrd,
but I've had no success in trying to get ybin to update the
/boot/yaboot/* or mkinitrd. I welcome any suggestions, even an entirely
different approach...
Thanks!
