Comment 32 for bug 638384

Since it's possible to supply the hwpack hashes to l-m-c to get rid of the warnings, I would think this is complete. The remaining question when I implemented this was how to assist the user so they don't have to download all the files themselves.

That piece has been implemented in linaro-fetch-image(-ui) where the user also gets assistance importing the keys if necessary.

Is there anything else that is needed?
