- YZF 2y agoThey're all good questions. The thing that reads the config should have been fuzz tested with something like AFL. Likely should have a lot more tests. Maybe shouldn't run in a device driver. There's almost no doubt there are engineering process and culture issues here. And then absolutely the release process. Rollback is hard I guess once your OS can't boot.

This is why the client needs have enough error handling to realise it's latest update has now caused unsuccessful boot and roll that update back locally to the last known good configuration (or completely back to factory and pull all updates again).
