Manually at least, this wasn't too hard: I ran linaro-media-create, copied the boot images onto a separate SD card to install them, then booted with the real card in a card reader attached via USB -- this works much better+faster than straight booting from the on-board MMC slot, and has the advantage that SDHC cards (or USB stick / HDD etc.) can be used. Especially if we configure the root device into the bootloader as root=UUID=<uuid>, Linux should be able to find the root fs wherever it is. Is this feasible?
