Please feel free to file a feature request on bugzilla for us. Right now we're more concerned with basic things like getting an install bug
free. This is an interesting thing, however. I think software RAID can be done without the initrd having LVM support in it. It has to do
with partitions being marked a certain way.
using strategies listed here: http://wiki.clug.org.za/clugwiki/index.php/RAID-1_in_a_hurry_with_grub_and_mdadm
notably "Make the hda partition types "RAID auto-start"..."
Anyways, we'll be getting to these "fancier" features eventually :)

Progress isn't made by early risers. It's made by lazy men trying to find easier ways to do something.
