Stock Redshift does not load custom configuration

**Describe the bug**
Redhisft comes with the system, but it is not configurable. Its default colour temperatures are 6500 for the day and 5500 for the night, which I find unsuitable. I have created a configuration file which works perfectly well if I start Redshift manually, but which appears to be ignored by the instance that starts automatically with the system.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a redshift.conf file in your home directory (`/home/user/.config/redshift.conf`)
2. Reboot

**Expected behavior**
The redshift.conf file is read and settings are subsequently applied.
