[arch-general] root login @ console

[Jack Frost]

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???
