Note that all of these are command-line options already.  His diff just
changes the default.

Either way, I think it might be hard to deal with.  The problem is
exactly that the partition table *is* recursive (meaning that one of the
partitions contain the partition table itself) -- intentionally.
Operating systems don't seem to have an issue with it, but (g)parted does.

The offset option allows one to generate a different table, but then one
has to mount the whole device (e.g. /dev/sdc) not the partition
(/dev/sdc1) -- which also means that one can't use the remainder of the
device as a disk partition.
