Hello Uwe and Erico, thank you for sharing your ideas and scripts. Inspired by your input, I could solve the problem with a custom rule and a pre-script: ==== custom rule: ==== cd /sys/block let disks=0 for dev in sd[a-z]; do readlink $dev | grep -q usb && continue let disks++ echo "s/__diskdev${disks}__/${dev}/g" >> /tmp/realdisks.sed done if [ $disks = 1 ]; then echo -n "sdsys" else echo -n "raidsys" fi ==== pre-script: ==== sed -f /tmp/realdisks.sed /tmp/profile/autoinst.xml >/tmp/profile/modified.xml The single disk installation ends up using /dev/disk/by-id/... in /etc/fstab and /boot/menu/grub/menu.lst. The raid installation uses /dev/mdx in these files and UUIDs in /etc/mdadm.conf, so all should be ok.
