Hi Vinayak

I believe that the best way to prepare debug and prod images is to create
include file (.inc) with base set of packages and features and then add two
.bb recipes, one for prod and one for debug - every of this recipes will need
to include the `.inc` file. You could name them `base-image-prod.bb` and
`base-image-debug.bb`. This way you could run either prod or debug builds
by running `bitbake base-image-debug` or `bitbake base-image-prod`.

As for the machine, this would need to be set in local.conf every time you want
to switch the machine.To simplify this process, for the management of the
configuration of the entire build (including the selection of debug / prod image
or machine configuration), I recommend the kas[1] project with the very helpful
kas-container tool.
