The original value of each device's format attribute is stored after
the device is probed/scanned/detected. An optional/keyword argument,
orig, is added to StorageDevice.setup so that the caller can specify
whether to set up the device using the current/new formatting or the
original formatting. StorageDevice.destroy methods automatically use
the original formatting.

Hi,

This looks like a bit of a disruptive change, but necessary so ack.

Regards,
