The main problem with this approach is that dd is incredibly slow, especially with large disks. I used it to clone a 250MB disk recently, ran it overnight and it was still going the next morning :( You can speed dd up by increasing bs, but this documents warns about using the wrong block size. Even so, you are cloning the unused space on the disk too, so it will always be inefficient. Partition image is a much better way of cloning filesystems, as long as the target partition is at least as large as the source. If the target partition is larger, you end up with a filesystem the same size, which you enlarge to fill the partition with resize2fs/resize_reiserfs/xfs_growfs/whatever. -- Neil Bothwick If a book about failures doesn't sell, is it a success?
