[Nut-upsuser] /var/run/nut directory not created on CentOS 7.2 with systemd

[Mark Hansen]

Hello,

I'm configuring the NUT package which comes with CentOS 7.X:

nut.x86_64                              2.7.2-3.el7                        @epel
nut-client.x86_64                       2.7.2-3.el7                        @epel

I've configured NUT based on the instructions found on this page:

https://www.luzem.com/2015/01/25/install-ups-in-centos-7/

which worked, except for one problem. When starting the services (nut-server, nut-monitor)
the /var/run/nut directory is not created, and so the service fails to start.

If I create the directory manually, using the following commands, I can get the services
to start, but upon re-boot, the directory is gone and the services fail to start again:

mkdir /var/run/nut
chown root:nut /var/run/nut
chmod 770 /var/run/nut
restorecon -v /var/run/nut

I searched and it seems the issue is that /var/run is on a temporary filesystem, so stuff
created there do not survive a reboot.

To work around the problem, I've created a start-up script (/usr/local/sbin/rc.local) and
create the directory there. This seems to work, but I'm thinking there is something wrong
or missing in my configuration.

What is the correct fix?

Thanks,
