3Supports rewriting `super.img`, `boot.img`, and `initramfs.img` based on
4`launch_cvd` arguments. In a multi-device configuration, there is only one
5`assemble_cvd` invocation, but multiple `run_cvd` invocations, one per device.

7The disk files produced by the Android build system are arranged into a
8"[composite disk]" and protected with a read-on-write [qcow2] overlay.
