Thanks for the response, but I think I already understood that part.
I guess my question was that, if your array has to be configured in /etc
rather than autodetected, how is that configuration transferred into the
initramfs (which we'll assume is on a non-RAID /boot)? This may be a
questions with as many answers as there are distros.
GRUB2 supposedly supports booting from any RAID level linux supports.
