- What I did
I modified the fast-reboot script to check that certain ASIC configurations haven't changed between the source and destination SONiC image before performing the warm reboot.
- How I did it
sonic-net/sonic-buildimage#3384 adds the relevant checksums at build time. I wrote a script to fetch these checksums from the filesystem and check that they match. This script is called as a pre-check in the warm reboot script.
- How to verify it
I built two SONiC images with the same checksum and verified that warm reboot proceeded normally. I also built a third image with a different checksum and verified that warm reboot was aborted when attempting to boot from one of the other two images.
