Error
There are multiple users with the same UID ("0") in the file /etc/passwd.
Correct them manually before running the YaST users module again.
Oh yeah? Pbbbbbbt! There are two users with UID 0 because there are two people with root access to this box, and one prefers bash while the other is much more comfortable with tcsh. Two usernames for root in /etc/passwd differing only in the choice of login shell, quite intentionally, thank you. :-P
Fortunately, I can deal with user/group administration just fine without using YaST -- which is how the second root user got in there. (I remember when I used to do every step by hand, without the use of a newuser/adduser script.) I was just curious how the YaST user administration screens looked and whether they're actually easier for me than doing things the way I'm used to. Which is entirely possible, if YaST doesn't enforce assumptions that get in my way ... er, like this one here.
(Yeah, I know, we shouldn't be logging on as root; we should log in as normal users and use 'su'/'sudo' to do administrative tasks. It's a throwaway installation to get used to this distro, make sure the box works, and play with a couple of packages before deciding exactly where in the network this machine is going to go (most likely meaning: which existing machine it'll be an upgrade for) and doing a detailed configuration to fit that purpose and mesh with the rest of my network. So for the moment, I'm logging in as root -- or rather, as 'rootcsh' -- and not feeling guilty about it.)
