Nagendra,

It really sounds like a missing feature, doesn't it? It should be
possible to manually add overlay to your build (or at least have means
for doing it). @Remi, @Antonio, @Stevan - how much effort would it
take to add such feature? The use case is:
- download your images using 'downloads'
- prepare overlay
- expose overlay path so user can add overlay to the image(s) in
dockerize postprocess.
I would gladly use it as downloading and decompressing overlay takes
ages on some of my boards.

Best Regards,
Milosz
