Yeah...I'm not going to hand jam it. While I am perfectly capable of restoring from a backup and rebuilding, I choose to continue waiting for mdadm to be added to the live image. I can boot to the live disc, install mdadm, mount both md0 and md1, see what is in there...but I don't want to leave fragments of stupidity behind installing to one ext4 partition and then trusting mdadm to rebuild the entire thing onto the other drive after the fact.
mdadm or not, drives are more likely to fail during a rebuild than any other time just because of the heavy load and heat applied.
What is more interesting to me is that somebody wrote the how to for ubuntu. My particular machine is currently running (ancient) ubuntu with a pair of raid drives. I know I didn't have to hand jam that one. And that has been migrated, right over the top, from fedora, to suse, and then to I think 3 different ubuntus. I will wait (beg) for a couple of smart guys to add md devices to the installer.
