Thanks. Here’s the result when I tried that:
user@machine:~$ sudo systemctl status mongod
[sudo] password for user:

WantedBy=multi-user.target
It may just be my lack of knowledge about linux but I don’t see the sort of statement your describe. There is the line:
ExecStart=/usr/bin/mongod --config /etc/mongod.conf
but that’s the same config file I earlier wrote of wanting to be able to change–but when I do so, mongod will not start.
Is this line important?:
EnvironmentFile=-/etc/default/mongod
The thing is, I don’t know what the leading - is doing there. There’s no file at:
/etc/default/mongod
