GNU cfdisk 1.0 does not show labels of partitions on /dev/hda. I mounted the
grml-64_0.1 partition (as /mnt/grml-0.1_64_iC2_, so the label was found and used
by the script that sets up the mount points) and started cfdisk 2.12r from there
- it shows all labels correctly. All partitions have been created with cfdisk
2.12 as "maximized", except  /dev/hdb2 and /dev/hdb3. All partitions except
/dev/hdb8 contain filesystems with labels.
Possible solution: Use cfdisk 2.12r instead of GNU cfdisk 1.0.
