Remember that we have two lists of devices - regular devices and system devices. The stopping and starting (or freezing and thawing) that I'm talking about is only for regular devices. System devices are not even touched at all before writing the image, so that behavior wouldn't change. Note, though, that is likely a bug, since we don't appear to be saving any system device state..
