Why does changing a init.d service start script makes no difference? The /etc/init.d/ script has a stale ExecStart

Question

No matter what value I set in the line DAEMON=/home/odoo/odoo/odoo-bin it always runs the old process in ExecStart. In other words, my changes aren't applied. I am running sudo nano /etc/init.d/odoo and then sudo service odoo start and it never applies my changes.

#!/bin/bash

I tried changing

 DAEMON=/home/odoo/odoo/odoo-bin

to

DAEMON=/home/odoo/odoo/odoo-binFAKEPATH

then ran:

sudo service odoo start 
sudo service odoo status

But I still get:

● odoo.service - odoo
    Loaded: loaded (/etc/systemd/system/odoo.service; disabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Wed 2018-04-11 21:45:20 CDT; 2s ago
   Process: 4467 **ExecStart=/home/odoo/odoo/server/odoo-bin** --config /home/odoo/odoo.conf (code=exited, status=203/EXEC)
 Main PID: 4467 (code=exited, status=203/EXEC)

What I was expecting to see:

ExecStart=/home/odoo/odoo/odoo-binFAKEPATH

Answer 1

Changing that file did nothing. I was editing the wrong file. I had to also update

sudo nano /etc/systemd/system/odoo.service

since my system uses systemd not init.d
