Currently it's not possible to do `haproxy.service` on RedHat-based distros (like CentOS). Initscript doesn't use this file at all, so it's not needed to create it anyway.
Actual result:
```----------
ID: haproxy.service
Function: file.replace
Name: /etc/default/haproxy
Result: False
Comment: /etc/default/haproxy: file not found
