I don't know about that error. To avoid some filesystem-media-related
problems, I have kept the factory formatting on my USB devices as
recommended here,
http://wiki.laptop.org/go/How_to_Damage_a_FLASH_Storage_Device.

I have a 16-GB SanDisk Cruzer and 16-GB Toshiba USB drives. I once manually
reformatted the SanDisk to remove the U3 partition, but after reading the
article, I got the SanDisk utility (
http://kb.sandisk.com/app/answers/detail/a_id/240/kw/usb%20flash%20drive%20u3/r_id/101834)
to
restore the factory format. For the record, the SanDisk device is formatted
as W95 FAT32 (0x0b), and the Toshiba - W95 FAT32 (LBA) (0x0c) according to
my disc utility.

No, the script works from either installation method. I sometimes test with
the Windows Live USB Creator.

New work:

I've added some user input checking and played with the
/home/liveuser/.sugar/default/owner.key and .key.pub files (which don't seem
to be installed by the Windows Live USB Creator).

These new lines before and after the copy of the overlay file,
+      chown root:root /home/liveuser/.sugar/default/owner.key
/home/liveuser/.sugar/default/owner.key.pub
+      mv /home/liveuser/.sugar/default/owner.key $USBMNT/$LIVEOS/owner.key
+      mv /home/liveuser/.sugar/default/owner.key.pub
$USBMNT/$LIVEOS/owner.key.pub
+      cp $CDMNT/LiveOS/$OVERLAYFILE $USBMNT/$LIVEOS/$OVERLAYFILE ||
exitclean
+      mv $USBMNT/$LIVEOS/owner.key /home/liveuser/.sugar/default/owner.key
+      mv $USBMNT/$LIVEOS/owner.key.pub
/home/liveuser/.sugar/default/owner.key.pub
+      chown liveuser:liveuser /home/liveuser/.sugar/default/owner.key
/home/liveuser/.sugar/default/owner.key.pub
+      chmod 600 /home/liveuser/.sugar/default/owner.key
+      chmod 644 /home/liveuser/.sugar/default/owner.key.pub

had the result that the newly booted cloned image presented with a new Sugar
user screen.  Once the Home view appeared, the old Activity icon colors and
Journal were present.  Be careful though, because a saved password cookie in
Browse for my Gmail was transferred to the new image.

The new, Sugar-specific script and diff are attached.

Thanks for testing!
