      Mongo 2.6.x sysv init script for EL6 isn't working correctly on 6u6. This is the output that standard start call returns:

      # /etc/init.d/mongod restart                                                                                                                                                           
      Stopping mongod:                                           [  OK  ]
      Starting mongod: /usr/bin/dirname: extra operand `2>&1.pid'
      Try `/usr/bin/dirname --help' for more information.
                                                                 [  OK  ]
      

      Problem is that RedHat changed /etc/rc.d/init.d/functions, in a way that function __pids_var_run() contains new entry:

              local pid_dir=$(/usr/bin/dirname $pid_file)
      

      This is wrongly interpreted in daemon() function that Mongo uses. Problem is that $base is considered complete line:

      "$NUMACTL $mongod $OPTIONS >/dev/null 2>&1"
      

      This causes side effect:

      + base='null 2>&1'
      + __pids_var_run 'null 2>&1' '' 
      + local 'base=null 2>&1'
      + local 'pid_file=/var/run/null 2>&1.pid'
      ++ /usr/bin/dirname /var/run/null '2>&1.pid'
      /usr/bin/dirname: extra operand `2>&1.pid'
      Try `/usr/bin/dirname --help' for more information.
      + local pid_dir=
      

      and thus spitting out errors.

      Solution is to use '--check' parameter for daemon() call. Here is proposing patch:
