That should create 7 partitions of which 5 have a file system. However, when I flash the emmc with it and boot the device:
# fdisk /dev/mmcblk1
Disk /dev/mmcblk1: 3.62 GiB, 3867148288 bytes, 7553024 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x0813790a

There is another partition that essentially overlaps the last two. That makes no sense.
That makes sense for DOS partitioning; there can only be 4 primary partitions, so number 4 is marked as an extended partition with the total space of the further logical partitions.
