Hi Tom, 

Would you mind to share with me how you make the installer image using wic?

    I'm confused as to why we need most of these changes to support the end
    goal.  The enhancement to bootimg-efi makes conceptual sense.  I don't
    see why we need a new plugin to do the rest, however.  What's being
    done
    here that we don't already do today?  I say this having made installer
    images for EFI machines using wic (in sumo, even).  Thanks!
