I'm trying to do a nand install as well and can't seem to get it to boot. I've tried installing Android and then Lubuntu server 2.0 and then running the nand-sata script and still not working. I also tried with ct-lubuntu-server-20131026/. I also changed the script line
mkfs.vfat -qF /dev/nand1 >> $logfile 2>&1
to
mkfs.vfat -F /dev/nand1 >> $logfile 2>&1
I've noticed I sometimes get this error when launching the script as well. I've no idea how to fix the mbr on the nand so any help appreciated.
