Yes. My current desktop does this. It was very simple, just requiring that I run grub-install on /dev/md0 and then adding insmod lvm and mdraid to grub.cfg. You also must ensure that you have a partition that is flagged bootable with some BIOSs.

If yes please give me some advice how to do it, i want to add full grub2 support to archboot setup and the docs are quite messy. I haven't found a way to do such a setup. Many thanks for any input. greetings tpowa -- Tobias Powalowski Archlinux Developer & Package Maintainer (tpowa) http://www.archlinux.org tpowa@archlinux.org
