Yes, that's the idea. I would add a safety check though:
even though the 'c' partition is defined and reserved to
mean the whole disk, there's nothing preventing creative
souls from using the 'c' partition for something else. I
would add a check to make sure that the offset of the 'c'
partition is less than or equal to any of the offsets in
the partition table before subtracting.

I think It's better to remove the options (and code) altogether.
