CentOS - Dec 2015 - systemd-sysctl not running on boot

Hey all,

After upgrading to CentOS 7.2, non of my servers run systemd-sysctl on boot.
So far, I tried running manually /usr/lib/systemd/systemd-sysctl, it runs
smoothly and updates all the parameters.
I also ran sysctl --system, which also executes successfully.

I checked within systemd, and systemd-sysctl is wanted by the
sysinit.target which is wanted by the multi-user.target - the one I boot
into.

I can't find anything by doing journalctl | grep sysctl
Or by looking through /var/log/messages (I run rsyslog as well).

Any idea's ?

Thanks

Works here...
# systemctl status systemd-sysctl
? systemd-sysctl.service - Apply Kernel Variables
    Loaded: loaded (/usr/lib/systemd/system/systemd-sysctl.service; 
static; vendor preset: disabled)
    Active: active (exited) since Wed 2015-12-16 20:19:10 PST; 6 days ago
      Docs: man:systemd-sysctl.service(8)
            man:sysctl.d(5)
   Process: 652 ExecStart=/usr/lib/systemd/systemd-sysctl (code=exited, 
status=0/SUCCESS)
  Main PID: 652 (code=exited, status=0/SUCCESS)
    CGroup: /system.slice/systemd-sysctl.service

You are correct, I'll refine my problem,

By running "systemctl status systemd-sysctl" I also receive the same
output, but a simple "cat /proc/sys/vm/swappiness" returns the default
value, and not the one set by my conf file.
But, if I run "/usr/lib/systemd/systemd-sysctl" the "cat
/proc/sys/vm/swappiness" does return the correct value.

Any idea ?
Does this happen to anyone else ?
