You copy the whole disk image which includes the partition information and boot block.

That does mean you need sufficient storage to image the complete disk. For me that means a minimum of 32G of memory since that's my typical card size.

The initial copy takes a long time.

Then you can use this script: https://github.com/Drewsif/PiShrink to shrink the image down to the minimum size needed. The end result is an image (usually about 4G in size) that when flashed to a new card will autoexpand just like the standard RPi images.
