For the system partition, we should reuse the code of the current "Clone
& Install" action of Tails Installer.

For the persistent volume, I would be tempted to propose to open both
persistent volumes and do an rsync, as doing a bit-by-bit copy will most
likely be prone to fail across USB sticks of different models and
different vendors (they might not *really* have the same exact size).
