For what it is worth, you may want to double-check via chkconfig. I once told initial configuration of a CentOS box to disable SELinux, only to discover chkconfig still had it enabled. As soon as I told chkconfig to disable it, it was off. Same for the firewall. During initial config, turned it off. chkconfig revealed it was on. I manually told chkconfig ip6tables off and iptables off, and only then did it stick. It is worth double-checking these things - a simple chkconfig --list|grep :on to see what services are on they you may _not_ want on, and maybe, conversely, chkconfig --list|grep :off to check disabled services you may _want_ on.
