the big thing with any of these new service managers (I'm more familiar with Solaris SMF than systemd, but I believe it does the same thing), is that it determines whether the service properly starts and tracks service dependencies. sysVinit style services could only be sequenced (start all lower numbered services before starting this one) and it had to wait for each service to start before going onto the next, while SMF and presumably systemd will start multiple services in parallel as long as they aren't dependent. also, SMF at least detects when a service fails/stops, and attempts to take corrective action per how that service is configured
Thank you for the enlightening information.
