Quick and kludgy. Partition an SD card of the correct size, rsync your data to it, then dd that card. Any other method you use will require you to have a smaller SD card to test the resultant image, so you may as well use that as the source and know it works. -- Neil Bothwick Things which must be shipped together as a set, aren't.
