Eddie,
Thanks again, but I think there is one little step missing from the
instructions. I gather that, if the dd of the fastboot image changes
the partition on the SD card, one has to reboot before proceeding,
just as if you had altered the partition table using fdisk. If you
don't, fsck fails because part3 does not exist.
As promised, here is:
How I created an SD Card for the TS-7260, YMMV:
# gain access to the USB Flash Drive
loadUSBModules.sh
mount /dev/scsi/host0/bus0/target0/lun0/part1 /mnt/
#
# Setup the SD Card to be boot-pivot-able
#
date "+%D, %T - Downloading SD Card Image"
cd /mnt/sts
wget -q

Q.E.D.
The redboot sequence above is essentially the "Load a kernel and initial
ramdisk to RAM from a TFTP server" from
http://www.seiner.com/ts7000/index.php/Booting%20to%20SDCard
Once you are happy with this kernel, initrd, and distro combination,
move onto the remaining steps, ultimately booting the new combo
automatically via redboot fconfig.
Cheers,
jw
