How to keep a pre-install script partition scheme?

Hi, Our requirement for partitioning is not covered by autoyast (IMHO) so I've had to use a pre-install script that uses sfdisk to create what we want - create / as a primary partition, an extended partition with swap and the rest of the disk as another partition (later to be mounted as /scratch for obvious reasons), but not all of the HDDs we have can take a / partition of 10GB so sometimes we need not to create a 3rd partition and to reduce the size of /. I've added the script that does this to end of this email. Unfortunately this does not work. I am assuming I have messed up my partition XML - can you help? I am now going to try using the "Auto-detection of partitions to be kept" method while I wait for a reply. partitions before install (using exec /bin/bash -x so that I get an interactive prompt to be able to check that the pre-install script has worked): Disk /dev/hda: 9729 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/hda1 0+ 1305 1306- 10490413+ 83 Linux /dev/hda2 1306 9728 8423 67657747+ 5 Extended /dev/hda3 0 - 0 0 0 Empty /dev/hda4 0 - 0 0 0 Empty /dev/hda5 1306+ 1434 129- 1036161 82 Linux swap /dev/hda6 1435+ 9728 8294- 66621523+ 83 Linux partitions after install: Disk /dev/hda: 9729 cylinders, 255 heads, 63 sectors/track Warning: extended partition does not start at a cylinder boundary. DOS and Linux will interpret the contents differently. Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/hda1 0+ 1305 1306- 10490413+ 5 Extended /dev/hda2 1306 9728 8423 67657747+ 5 Extended /dev/hda3 0 - 0 0 0 Empty /dev/hda4 0 - 0 0 0 Empty /dev/hda5 1306+ 1434 129- 1036161 82 Linux swap /dev/hda6 1435+ 9728 8294- 66621523+ 83 Linux which is a bit of a mess so no wonder the installatin cannot succeed.

From reading: http://www.suse.de/~nashif/autoinstall/9.1/html/CreateProfile.Partitioning.h... I thought I had understood the XML I needed to use to be:
