apacheds.service script not running from systemctl correctly

Hello,

I'm not sure if this is more of a general bug with Systemd/systemctl, but the apacheds.service file doesn't seem to read the EnvironmentFile variable, or at least doesn't act upon the variable therein.

While trying to start the apacheds service from systemctl I get the following errors:

----
bswan@ds:/lib/systemd/system$ sudo systemctl start apacheds
Failed to start apacheds.service: Unit apacheds.service is not loaded properly: Invalid argument.
See system logs and 'systemctl status apacheds.service' for details.

After much experimentation the work-around to get it working is to just copy the environment variables from /etc/default/apacheds and paste them into their appropriate places in the apacheds.service file and put the entire thing on one very long line.
