    This prepares partition 1 for the boot loader, partition 2 for the initial

-   To recap, below we would populate partitions 1 and 3 with adapted replicas
-   of partitions from the image downloaded above, then we would prepare the ZFS
-   pool and dataset layout on partition 2 and transfer the files from partition 3
-   (it should fit well, more so if you enable ZFS compression).
+   Below, we populate partitions 1 and 3 from the image downloaded above,

+   to the pool.  As the ZFS partition is sized the same as the original image,
+   everything should fit; while filesystem overhead may be different, the
+   original image is not completely full, and ZFS has compression enabled.
 
-   Finally, we would remove partition 3 and expand the ZFS pool (and partition 2)
-   to consume all the disk after it.
