Not sure I'd agree with you about the howtos being nice. They mostly deal with trying to boot from a RAID array (don't want that, as I have my OS on a non-RAID 120GB SSD). They're also contradictory, with some saying I need dmraid, and some saying not. Most seem to make no more than a passing nod towards genkernel. So, given that from the links that I've found, here's my starting set of questions. In /etc/genkernel.conf, which options do I need to enable. One guide suggested the following settings DMRAID="no" MDADM="yes" MDADM_CONFIG="/etc/mdadm.conf" MDADM_VER="3.1.4" If this is correct, does it matter that my mdadm version which I emerged is 3.1.5? The tarball in /var/cache/genkernel/src is mdadm-3.1.4.tar.bz2 Should I copy mdadm-3.1.5.tar.bz2 from /etc/portage/distfiles into there and rebuild genkernel. Do I need the dodmraid option compiled into genkernel, or is that only for fakeraid, or situations where I need to boot from a raid partition? Do I need the dodmraid option set true in the grub.conf file, or is 'domdadm' more appropriate? Jeff
