With the deb repository on 10gen comes an `/etc/init.d/mongod` script that throws errors when started and `numactl` is available as a command:

root@whisky:/home/derick# /etc/init.d/mongodb start
 * Starting database mongodb                                                   start-stop-daemon: unrecognized option '--interleave=all'
Try 'start-stop-daemon --help' for more information.
                                                                        [fail]

This comes due to the fact that in line 125, the following code: *--exec $NUMACTL $DEAMON* turns into *--exec /usr/bin/numactl --interleave-all /usr/bin/mongod* and stop-start-deamon does not understand *--interleave-all*.

(Also, shouldn't mongod be in /usr/sbin?)
