For this purpose I'd make a mount directory on another partition, e.g. /home/mnt, and remount / there: mount --bind / /home/mnt Then you can copy the files in root from there (/home/mnt) to your new root-partition without the trees mounted in /. Take a look into /home/mnt, the directories under the mount points are all accessible. But for any partition avoid to copy the /lost+found (if using ext4, e.g.) directory. When done just "umount /home/mnt". > The only pitfall I can think of right now is if you copy > filesystems using dd you end up with multiple filesystems with the same > UUID.
