>> /var/run directories are not created properly
>what specifically do you mean by this? just that you see log errors?
Following directories were not created automatically, I had to create
them manually in order to enable services to start:
/var/run/fail2ban
/var/run/screen
/var/run/sshd
/var/run/zabbix
Following directory was created, but its ownership was not proper:
/var/run/redis
> What's the output of:
> $ sudo find /run -ls
Please see attached file: sudo_find_run_ls.txt (working situation) and
find_run_ls_after_reboot.txt (after the system was rebooted i.e. not working
situation).

To make this a bit more complete, I removed the 0000var.conf and restarted the
system. When I checked the md5sum of files /usr/lib/tmpfiles.d, they matched to
my other Ubuntu 16.04 server.
After reboot, syslog relevant parts showed following:

This caused, that sshd, redis, fail2ban and zabbix agent were not able
to start.
In order for me to make the system usable, I needed to perform following
steps:
1) Log in to system using the serial console from the VPS control panel.
root@vspk:/var/run# ls -la /var/run
lrwxrwxrwx 1 root root 4 May 14 2018 /var/run -> /run
Contents of /run directory:
root@vspk:/var/run# find /run -ls > /home/kalle/find_run_ls_after_reboot.txt
(attached)
2) Give following commands:
root@vspk:/var/run# mkdir sshd
root@vspk:/var/run# /etc/init.d/ssh start
Starting ssh (via systemctl): ssh.service.
--> Now the system can be again accessed through SSH.
After that:
kalle@vspk:~$ sudo mkdir /var/run/zabbix
kalle@vspk:~$ sudo chown zabbix:zabbix /var/run/zabbix
kalle@vspk:~$ sudo chown redis:redis /var/run/redis
kalle@vspk:~$ sudo mkdir /var/run/fail2ban
kalle@vspk:~$ sudo mkdir /var/run/screen
kalle@vspk:~$ sudo chmod 777 /var/run/screen
