Yes you're right that 'guestfsd' running in the guest cannot change
the partition table seen by the kernel when partitions are mounted as
filesystems.  This would require some changes to the kernel.

I was just pointing out you can use libguestfs "live" now and do a
huge range of filesystem operations, including changing the partition
table on disk.
