Before starting any new upgrade/update/release, it is the common practise to take a whole image backup of the current working state. So that, if any thing goes wrong it can be easily rolled back within hours if not minutes. 

I am 100% sure there is some thing fishyyyy going on which KRAKEN is not telling us and that is what making all of us upset.  Bottom line is, KRAKEN is not telling us the 100% tryth about what is actually happening.
