We put in serial either
1. the UUID Engine send to us
2. the host UUID as returned by our getHostUUID utility function

the latter is unlikely to change, even after this disk move.

So the first suspect in line is Engine

Arik, do you know if Engine is indeed supposed to change the UUID in this flow?
That seems very surprising.

Thanks and bests,
