Overview
This document describes the procedure of configuring a systemd service by injecting custom environment variables into its environment. The document assumes we're configuring a service named "myservice".
Create the Configuration Directory and the Configuration File
Create a directory /etc/systemd/system/myservice.service.d. Inside that directory create a .conf file. Multiple files are allowed. These files contains configuration overrides for any part of the unit shipped by the distribution.
A file that contains environment variables could be named env.conf. myservice.conf is also an acceptable name.
Note that if the configuration directory exists and is empty, the service will be disabled.
