I understand the need for an easier way to create images. However, I feel like is the wrong place for =E2=80=98system=E2=80=99 and =E2= =80=98target=E2=80=99: the image format, conceptually, has nothing to do with whether we=E2=80=99re cross-compiling, compiling for a specific system, etc. It also seems wrong to me that =E2=80=98--image-type=E2=80=99 would, in som= e cases (but not all?), override =E2=80=98-s=E2=80=99 and =E2=80=98--target=E2=80=99. I feel like we=E2=80=99re missing an abstraction that would build on top of images, but I=E2=80=99m not sure what that would look like. Thoughts? Ludo=E2=80=99.
