RHEL 7 ships with systemd and the old init scripts are now implicitly mapped into systemd service units during boot (see the file /etc/init.d/README on your Beta installation for more detail).
We'd like to hear about your experiences with systemd on RHEL 7 Beta. We've maintained the
service command so that we don't break existing scripts that stop and start services, but systemd offers much more than just some backwards compatibility.
Let us know what you find!
