I will add the uses cases in v2. The current use case is to add tooling
or configuration items to a unified kernel image during runtime from a
encrypted disk.
Additional uses cases are adding additional tooling to read-only root
systems for example add gdb or strace to a production image
or enabling ssh.
Also systemd-reparted could be used as an alternative to wic.
