Comment Only adds complexity (Score -1) 385
As a RHEL server admin, the only thing I see systemd adding is complexity. Do a fresh install and compare it to RHEL5 or 6, and you have way more stuff running, new start/stop methods for init scripts, weird NTP replacements, and a bunch of stuff that you don't need. Then you go and install your app, or something like Postfix (because you're building a mail server). Why do you need parallel boot? udev hotpluggery? a "logind" process?
