I wish to configure autoyast where /boot partition in target server to be on top of a mirror.
in script section i inserted this code mdadm --create /dev/md0 --level=1 --raid-devices=2 --metadata=0.90 /dev/sda1 /dev/sb1.
this script will run as preinstall script.
i can not create /dev/sda1 and /dev/sdb1 with this script.

i have only /dev/sda and /dev/sdb on target.

if i try to create / as lvm and /boot to be inside of this / lvm,then after the OS begin to be install on target the boot loader can not be copied in /boot.this to avoid the mirror case as above to /boot.
