If Icinga 2 fails to start with an empty reference to `$ICINGA2_CACHE_DIR`
ensure to set it inside `/etc/sysconfig/icinga2` (RHEL) or `/etc/default/icinga2` (Debian).
RPM packages will put a file called `/etc/sysconfig/icinga2.rpmnew`
if you have modified the original file.
Example on CentOS 7:
```
vim /etc/sysconfig/icinga2
ICINGA2_CACHE_DIR=/var/cache/icinga2
systemctl restart icinga2
```
