I moved forward - but not much - after understanding a bit more what cgpt was.
I ran the following, note the change of the -b flag to 64 per Andrew's advice:

DEV=/dev/sdb
sudo parted --script ${DEV} mklabel gpt
sudo cgpt create ${DEV}
sudo cgpt add -t kernel -l kernel -b 64 -s 32768 ${DEV}
sudo cgpt add -i 1 -S 1 -T 5 -P 1 ${DEV}
sudo blockdev --rereadpt ${DEV}

On my Linux machine this created a /dev/sdb1, but it was only created a 17MB /dev/sdb1. The instructions say "The signed image can now be written to partition 1 of the device (/dev/sdb1 in this example).". I interpret this to mean write armv7.img (From here: http://cdn.netbsd.org/pub/NetBSD/NetBSD-8.1/evbarm-earmv7hf/binary/gzimg/) to /dev/sdc1. However, given that it is only 17 MBs, it fails.

What am I doing wrong? Please assist.
