I only got this script to work on a "fresh" flash. I ended up just editing the files that mount and unmount the ext3 file system by hand. I created a symbolic link to just my home directory only. Just a note but after you extend the file system, Windows XP will no longer mount the drive when using the USB. If you are running only Windows, you should keep this in consideration. Linux has no problem, it mounts all partitions on the mmc. For some reason Windows will see the drive in "Disk Management" but not assign it a drive letter, and all options are greyed out. This is my experience anyway.
