how do I force the mongodb service to use /etc/mongodb.conf?

Related question, didn't fix the issue: MongoDB not using /etc/mongodb.conf after I changed dbpath

On Ubuntu 12.04. $ mongod --version = db version v2.4.9

I'd like the mongo service to use /etc/mongodb.conf (I thought it was set to do that out of the box but apparently not).

$ cat /etc/mongodb.conf | grep dbpath
dbpath=/home/xyz/mongodb

$ cat /etc/mongodb.conf | grep logpath
logpath=/home/xyz/mongodb-logs

$ ll /home/xyz| grep mongo
drwxrwxr-x  2 mongodb mongodb  4096 Feb 19 11:58 mongodb/
drwxrwxr-x  2 mongodb mongodb  4096 Feb 19 11:58 mongodb-logs/

(the instructions say it should be mongod user but that doesn't exist, while mongodb does, instructions incorrect?)

But whenever I start mongod it tries to use /data/db: 

ERROR: dbpath (/data/db/) does not exist.

I've looked in the init.d script and don't see any options for config path: 

$ cat  /etc/init.d/mongodb | grep config
# release without the 'show-config' command (introduced in
    initctl show-config -e "$JOB"|grep -q '^  start on' || DISABLED=1

When I restart the service it appears to immediately stop: 

$ sudo service mongodb restart
stop: Unknown instance: 
mongodb start/running, process 2495
$ sudo service mongodb status
mongodb stop/waiting

Is this a bug? It appears to be ignoring the config file. I know I can start it using --dbpath or --config, but shouldn't it be reading the config file if it isn't provided a dbpath? Since the service is failing to start (apparently) where can I find the error that caused it to fail?

I had a similar problem (on v3.2) which turned out to be due to an error in my /etc/mongod.conf. I had the following:

replication:
  replSet: rs0

which should have been:

replication:
  replSetName: rs0

Starting mongod via sudo service mongod start failed silently with nothing in the logs. Fixing the config allowed mongod to start.

This was actually on RHEL, and I verified that the init script was passing --config /etc/mongod.conf. I assume it's the same on Ubuntu.
