Variation on your theme. Uses ext2 and extlinux with no FAT partition.
Remove "-n" from sfdisk so changes are written. Adds some error
checking.:

Unfortunately the only system I have to test on at the moment boots the
installer OK, then asks for the installation media, but doesn't see the
USB device when Hard Disk is selected. With the FAT partition and
syslinux doesn't see the device as bootable at all.
