This allows extra space to be added after the last partition and is
especially useful when free space is needed for ex: adding partitions on
first boot with ex: systemd-repart[1] and the image is tested in QEMU.

Well that's certainly interesting.

Can you add a test case for this? That'd help also demonstrate how this
would be used over just having a minimal wks file and repart.d conf
files to describe the rest of the system. Thanks!
