@Luc-Novales What part of the task would you like to “dry-run”?
The whole process consists of many steps (as you see from the output in screen) and pretty much all of the steps depend on others. For example with the image set to resizable FOS needs to shrink filesystems and partitions before it can capture the new partition layout. There is not much point in dry-running the shrinking and then capture the partition table.
Or if you look at deployment. How would you not touch the existing partition table because it’s a dry-run but then try to test partclone deployment of the data. Simply impossible.
