Centos – stop Centos 6.3 loading ‘Text Mode Setup Utility’ at restart

I've just puppetted a virtual machine and from scratch (based on Centos 6.3 minimal). That install process does a variety of things, but one annoying side effect is that when the VM reboots, it automatically opens a tool called:

Text Mode Setup Utility 1.19.9    (c) 1999-200 Red Hat, Inc.

Is says "Choose a Tool" with options for "Authentication configuration", "Firewall configuration", "Keyboard configuration", "Network configuration". I don't think it serves a purpose as the VM is sufficiently well configured for what we need to use it for, but it's annoying that it doesn't restart to the normal login prompt.

Can anyone tell me how to stop this Text Mode Setup Utility running? Is it a missing configuration option or a spurious package I've installed?

Here's the output of chkconfig. It looks like firstboot is running. I didn't know what that is, but now I've read this manual page, so I'll touch /etc/sysconfig/firstboot, which should stop it happening?

Alas no. I also tried editing to /etc/sysconfig/firstboot to include the line RUN_FIRSTBOOT = no, as described at forum thread. But another reboot and the tool is still popping up. Can you tell me how to disable it? Also, might you cast an expert eye down the list of services running and tell me if there's anything else I shouldn't be running on a production webserver please?
