The default mongod instance is called "mongod" on RPM distros.
When running standalone, just re-use that name rather than creating one called "mongodb". Otherwise, you wind up with /etc/sysconfig/mongod and mongodb, two sets of init scripts, two sets of logs in /var/log/mongod, etc.
Configure the mongod instance name at the attribute level
