I suspect you're correct in that I'll end up with the boot partitions being in RAID1 and the data in RAID6, however I am seriously considering having the boot in RAID6 as well...if I can integrate the mdadm.conf into the initramfs properly I can't see a reason not to do this?
The initramfs is usually located on the boot partition. A raid1 partition with a filesystem can be read by the bootloader even if the bootloader doesn't understand to start the raid first. This is not possible with raid6.
So /boot is usually raid1.
Had a look at the metadata=0.9 option but reading the info on mdadm metadata I think I'd prefer to have the metadata at the start of the drive, also it looks like metadata=1.2 has extra functionality that I may want to use later.
Look at v1.0 superblock, it has the same functionality but stores the superblock at the end.
