    I'm following a thread in questions right now, and I must agree with
    some of the posts stating that using dd on the / filesystem could cause
    grief if the partition is mounted. You may want to use a fixit floppy or
    alternative boot method and then dd the disk to ensure no writes occur
    whilst in transfer.
