While I'm not sure about 7.0, Fisher (the 7.1 beta not intended for anyone but the purely insane) doesn't open any of the inet (xinetd is the super server) services until you explicitly tell it to do so. I even installed the OpenSSH server package from the beta distro and I still couldn't get in until I turned on the service. This is a nice break from the previous open windows until you locked them approach.
