To further clarify as I believe the meaning may have been lost in my phrasing (I apologize), the error you're receiving on boot indicates that SELinux was for some reason disable improperly (ie. not with the config files -- If the kernel looks for SELinux but it is gone, it will cause kernel or init halts, or even full-blown kernel panics.
Not sure how it would get disabled or changed without using the config files?
