There's already an IMAGE_MANIFEST file that's quite different from this?
tmp/deploy/core-image-minimal-qemux86-64.rootfs.manifest
base-files qemux86_64 3.0.14
base-passwd core2_64 3.6.3
busybox core2_64 1.36.1

So I find the name very confusing. Perhaps call this something completely
different, like "result" or do-image-task-output or similar...
