The Aboot bootloader relies of the SWI= keyword argument in the boot-config file to know which image to boot. This value is also used by sonic-installer to figure to extract the next image that will be executed. The current code has an issue as it only expects the next image to match the installation path of a SONiC image but not anything else. This means that `SWI=flash:sonic-aboot-broadcom.swi` is not valid and can therefore be a problem when trying to install a new image via cold reboot. Additionally a missing or empty boot-config would generate a python backtrace instead of gracefully recovering from this state.
