FWIW, I am running CentOS7 on 2 servers with ZFS on linux. They host the back end of my ESXi VM's. no issues. Not saying I like systemd at all though, for sure I do not - but mostly because I have to learn a new thing and it is kinda anti-linux in the first place (everything in its own place/space).

OK, so I have my own 2-cents worth and experience with systemd... In a nutshell, I do NOT like it. I have found CentOS 7 to have stability issues that are TOTALLY UNACCEPTABLE for a SERVER. (might be fine for a desktop, but NOT a server!) And therein lies the rub -- systemd is designed from the get-go to improve the "Desktop Experience" for Linux. Start faster, provide feedback faster, do more crap automated, and automatically "filter" logs and messages. All GREAT things for the NOOB running Linux for the first time on a desktop so they can run some app... But most of the RATIONALE for systemd is an anathema to running a server! In my own world, I have a CentOS 7 system running next to a CentOS 6 system. The COS7 system routinely breaks its network configs requiring me to re-run the firewall startup (otherwise, my virtual machines networking breaks at LEAST once a week! On top of that, I usually leave a "console" (not :0) running with a firewalled (e.g.: limited access by IP address) VNC connection -- and this too BORKS at least once a week (when this fails, I have to ssh into the box, stop the vncserver, remove the .X11 folder in /tmp, and restart vnc. Not a HUGE chore, but given that I leave that very specific interface up so that I can access VMs VERY QUICKLY in an emergency, it sucks that often I have to do just that when something is going on -- and the delay is frustrating. So what have I done about it? Personally, I'm sticking with CentOS 6 for servers. Period. I've tried and tried with COS7, and it just isn't right for a server. I have to think there will wind up being some "splits" in some distributions -- separating out server & desktop versions. Just my thoughts... me, the guy who had QMT running on COS6 for more than a YEAR before we (the QMT team) officially supported it... yeah, that guy... is DONE with COS7! We'll have to wait and see what the next rollouts are like from the distros -- but for now, COS7 is NOT VIABLE as a server in my opinion.
