Ubuntu startup files have an inconsistent directory for dbpath and logs

From the upstart file
if [ ! -d /var/lib/mongod ]; then
mkdir -p /var/lib/mongodb && chown mongodb:mongodb /var/lib/mongodb
fi
if [ ! -d /var/log/mongod ]; then
mkdir -p /var/log/mongodb && chown mongodb:mongodb /var/log/mongodb
fi
