Ivan,My response probable did not make any sense. I went and dug up a blog entry I made and reposted it. I covers the subject of how to make a /boot on a software raid one. It does not cover the install, but rather how to convert to a raid1 once you are up and running and how to install grub onto both (or all) members of the array. www.damtek.com
