I do this for every SD card onto which I myself write the partition table.

But I think the .zd files re-write the WHOLE SD card (including its
partition table).  If that is true, then the person replacing the SD
card has no control over where the partitions get placed -- only the
person who created the .zd file can customize that partition table.
