[arch-general] root login @ console

So I foo-bared my /home partition, no big deal, done it before, and I keep good backups. I boot to single mode and get to a prompt. My regular user is gone so I try to just login at the console (no X) as root. It doesn't work. I know I set the root password. What setting is preventing root from being able to authenticate. I noticed when I went to cups on localhost:631 and tried to do an admin task and needed to authenticate. Root couldn't login. How do I allow root logins under Arch/Arco linux at a console???
