Should work.  Don't take /proc in your tar backup. After you untar,
you should be able to 'chroot /mnt/sysimage', fix /etc/fstab to match
the new partition layout, either by adding labels to the filesystems
or changing the entries to use the partition device names.  Fix the
root= entry in the /boot/grub/grub.conf kernel line(s) if that
has changed, then you can run 'grub-install', exit twice and
remove the CD as you reboot.
