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
