Hi,
- From my experience it works with grub2 out of the box. Iirc, you do
not need to do anything special, just setup the raid in the installer,
install the system and let the installer setup grub2.
The stuff about /boot is for users with grub1 or other bootloaders not
capable to boot directly from mdadm-volumes (or lvm or whatever).
Another situation where you have to think about /boot is if your going
to encrypt your root using cryptsetup.
Afaik you even should even be able to use LVM on raid without much
trouble, but i never actually tried to do that.
