On Ubuntu 8.04.1 there can be spaces inside the initial bracketed uptime number after a reboot. These spaces disappear once the uptime is large enough. Therefore, use sed to filter out these spaces so that the cut command that extracts SD card size will always work. Signed-off-by: Christopher Hall <hsw@openmoko.com>
