> Implements an init system; does not replace DNS, syslog, inetd, or anything else. You're confusing systemd the init manager and systemd the project. systemd as an init system only "replaces" initd, syslog and udev. All other components under the systemd project are optional and not required, nor is there any push to make them required.
