| I then used my laptop and an SD card, created a single ext2 partition there and unpacked the preinstalled ubuntu rootfs. Copied the ''uImage'' to root and the created modules to ''/lib/modules''. Erased unneeded boot scripts (including ''network-manager'') from ''/etc/init/''. Created there a file to start ''getty'' on ''ttyS0'', 115200 baud.
