Description of problem: During firstboot, after setting Firewall settings and accepting, you get a warning: "Clicking the 'Yes' button will set the security level of the system and override any existing firewall configuration. Are you sure you want to do this?". Assumably there isn't any pre-existing firewall configuration, so I don't think this warning is necessary during firstboot. Version-Release number of selected component (if applicable): system-config-securitylevel-1.6.9-1 firstboot-1.3.53-1
There is an existing firewall configuration, though. anaconda sets up the system to have SELinux enforcing and only ssh open as a firewall hole. So s-c-securitylevel is doing the right thing in seeing that there is an existing config and warning about it.
I think defaults are different to an existing configuration set by a user. As far as the average user is concerned there isn't a pre-existing configuration and as such would be slightly confused by the message. At least changing the message on firstboot to something else like 'Clicking the Yes button will set the security level of the system. You have changed the defaults, are you sure you want to do this?' would make more sense.
