understood. I thought, you were trying to convert a sup offline and not in 
production.

There shouldn't be any different between manual & autoboot. If you have 
already cleared the boot string manually, they that should be fine.

What version of bootloader image you are using? There were some issues 
with older version of bootloader images specifically with booting from 
'sup-disk0:'.

Can you also send me (if you want you can unicast) the complete output of
a. your 'set..'
b. the complete console log of the RP failing the boot.
