Retaining software RAID devices during automated installation with autoyast

Hi Uwe,
Doing automated installation of server with / on ext3 on software RAID 1 mirror of /dev/sda2 and /dev/sdb2 and /home on xfs on software RAID 10 of /dev/sda3, /dev/sdb3, /dev/sdc3, /dev/sdd3.
I want to preserve /home when doing an automated reinstall of the machine. I can keep the existing partitions fine and they get assigned to MD devices correctly.
However whilst the partitions are being kept fine, I see the messages "deleting MD device" (or some such wording), followed by "creating MD device" (or similar wording) and indeed it then fails to mount /home as the xfs file system is not there any more. )-:
If I set <create config:type="boolean">false</create> for the partitions on the /dev/md device in the autoyast file then the md devices are still destroyed but then not created again so the install fails immediately as there is nowhere to install. )-:
Is this a bug or a feature?
Is there any way I can get autoyast to preserve the existing md devices?
If you want to see my autoyast partitioning section, this is it:

Btw. the disks are gpt as they are 3TiB disks...
PS. I am installing SLES 11 SP2 x86_64 if that matters.
Thanks a lot in advance!
Best regards,
Anton
