title: Mongo does not run when installed via mongodb-10gen package on Ubuntu 12.04
body: <p>So I've followed the Mongodb installation instructions here: <a href="http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/" rel="noreferrer">http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/</a>.  However, after installing, mongodb does not run when invoked with <code>start mongodb</code> or <code>/etc/init.d/mongodb start</code>.  After digging around and adding debug comments to <code>/lib/init/upstart</code> (!) I deduced that the problem is that the <code>mongodb-10gen</code> package inexplicably doesn't create an <code>/usr/bin/mongodb</code> executable for upstart to reference - it creates a bunch of other executables, but not that one.  What's going on?  Is the 10gen package broken?  Are the instructions wrong?  Or is something really, really, really bizarre going on on my system?</p>
  
  <p>P.S. Installing the <code>mongodb</code> package included with Ubuntu 12.04 works like a charm.</p>
