1. "make target/sonic-broadcom.raw" will create the compressed dd'able image.
2. This will also update the grub config files (device/dell/*/nos_to_sonic_grub.cfg) with the image versions.
* [rc.local]: Copy saved minigraph if available.
In case of sonic-to-sonic update old image stores minigraph under /host
directory. Upon first boot this minigraph will be used by new image to
save configuration.
