I disagree with the statement entirely because it is wrong. The
mainline kernel has supported 3Ware RAID controllers since Debian
Sarge if not earlier. 3Ware RAID sets are just big disks as far as the
installers are concerned.

Now, if they had presented it as "installing Linux onto a software or
fake RAID array" then I'd have bought it. Setting up the devices is a

I still think that btrfs has is the easiest of all. Just two commands.
You can do it on a live system. Assuming that you have /dev/sdb as the
existing device, /dev/sdc as the new device, and /mnt as the root of
the volume and you want to create a mirrored set:

# btrfs device add /dev/sdc /mnt
# btrfs balance start -dconvert=raid1 -mconvert=raid1 /mnt

Sit back and let it do its thing. I'm really liking what btrfs has done
and where it's going. It's doing all of the cool things AdvFS did 10
years before ZFS happened. AdvFS is still my favoritest file system
evar but Butter is getting close to surpassing it.
