moving the whole linux-system from one disk to another

There are a lot of way's doing this, I prefer this one:

1. creating the partitions needed on the destination disk
2. mounting the partitions, I prefer to mount the partitions pairwise (src + dest) under /mnt (/mnt/src + /mnt/dest)
3. syncing the filesystems with:

• sudo rsync --stats --progress --numeric-ids -aAhHSP  /mnt/src /mnt/dest/

4. installing the new disc, booting with rescue-media and chrooting into the 'new' system:

• sudo mount -o bind /dev /mnt/dev
• sudo mount -o bind /sys /mnt/sys
• sudo mount -t proc /proc /mnt/proc
• sudo cp /proc/mounts /mnt/etc/mtab
• sudo chroot /mnt /bin/bash

5. if needed, edit /etc/fstab and fill in correct uuid's or device-names
6. repairing grub-installation:

• grub-install /dev/sdx
• update-grub 

7. finally, leaving the chroot-env, unmounting all and booting into the new system
