Done :-) Still puzzled why this worked "automagically" before. I don't have the
time right now to check the repository for a change that might disable the
automatic expansion of all new devices, but I suspect something like this.
I see how it is safer if you trigger expansion manually. E.g. if you need to use
a bigger temporary disk untill your warranty replacement with the correct size arrives.

Best regards,
Patrick
