Auto-assembly and metadata are not related: I regularly use 1.2 metadata on non-boot partitions and they auto-assemble fine. However lilo won't boot on anything other than 0.9, this I found the hard way :) Kernel auto-assembly seems quite useful and desirable to me, especially when using, say, initrd to unlock dm-crypt partitions (no need to configure madadm.conf in the initrd). BTW, what is that 0xDA type?
