In what way does Linux need to know it is doing software RAID to boot from a
mirror? It boots the kernel, grabs the initfs from one of the drives, assembles
the RAIDs, pivots root to whatever I tell it, usually /dev/md0 which is just
another block device to the OS. Perhaps what you say is true if you want to
RAID 5 the boot drive but I would avoid that situation precisely to avoid such
complications.
