Hello. TL;DR Don't try to upgrade to 13 if you have a checkpoint on your boot pool. I spent three hour yesterday trying to fix a production server which would not restart after an upgrade. Even rolling back to previous version did not help. After trying almost everything, I was able to see, among a load of fast scrolling cryptical messages, "can not read checkpoint data". Turns out 13.1's loader.efi is not able to find a ZFS pool if it was checkpointed on 12.3. Perhaps this is widely known, but I had never seen any mention of this. Possibly this does not happen on non-UEFI systems. I hope this message can save a lot of trouble to others. bye av.
