[opensuse-autoinstall] SoftwareRAID on GPT disks

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello! I'm fighting for a week with autoyast and a SoftwareRAID partitoning on non-EFI servers with two 3-4 TB disks. I've figured out, that autoyast successfully applies my profile to the servers, as long as I don't set up a SoftwareRAID. Means, that autoyast creates automatically a bios_grub partition and installs GRUB2 correctly, the server is able to boot from a 2.7 TB root partiton. I don't need to do anything. As soon as I'm using a SoftwareRAID partitioning, autoyast doesn't create the above mentioned bios_grub partition and bootlader instalation fails, the operating system isn't bootable. It's possible to workaround this issue by manually creating the bios_grub partiton in the partitioning context and to manually enabling bios_grub to this partiton with parted in postpartitioning-scripts, nevertheless GRUB2 will show the same error messages as before, which can't be timed out using error context. But, operating system will boot up correctly from a 2.7 TB md device. I've attached my example partitioning with static 1MB bios_grub partition, 32GB swap, 1GB /boot, and max root partition: <partitioning config:type="list"> <drive> <device>/dev/sda</device> <initialize

unattended installation for a SoftwareRAID sceanrio, I'm hoping for a clean solution or a tip how to avoid bootloader context error messages, so no user interaction is needed. In fact other distributions like CentOS 6, Debian 7.0 and Ubuntu 12.04 don't show this issue, so I think, that this is a bug or limitation, not a general issue.
