Yeah. Fast. But sufficient only if i did not miscalculate again.
The full copy with 131072 chunks of 64 KiB from fully unmounted /dev/sdd*
would be the safer variant.

But at least we seem to have defaced the backup GPT which caused the
gdisk refusal after gdisk itself wrote it to that place.

The file size of rock-img-shrunk.img should now be 8,448,393,728 bytes.

If so, then it should be safe to let gdisk fix the problems which it
detected in the partition tables. But as said, this is of interest
mainly on the final storage device, where the backup GPT is a good
protection against mishaps by clumsy partition editors.

Should the booted system do that ?
Did i miss you mentioning this ?

Googling "rock64": The power of a 10 year old workstation in the size
of a credit card. Zero noise, i hope.
