| Doc Text: |
While autoassembling a MD raid, the dracut initramfs used an invalid parameter on calling mdadm from inside the udev to incrementally build the raid device. This would prevent the system to boot, if the root device is on a raid device and autoassembly of raid devices was chosen. The invalid parameter was removed and autoassembly for raid devices should now work for root devices from inside the dracut initramfs.
