      Description

      In 2.4.9, an _id index is not automatically created on the local.startup_log collection. In master, an _id index is created by default. This is a regression caused by the changes from SERVER-8412.

      2.4.9:

      > db.getSiblingDB('local').startup_log.getIndexes()
      		 
      [ ]

      master:

      > db.getSiblingDB('local').startup_log.getIndexes()
      		 
      [
      		 
      	{
      		 
      		"v" : 1,
      		 
      		"key" : {
      		 
      			"_id" : 1
      		 
      		},
      		 
      		"name" : "_id_",
      		 
      		"ns" : "local.startup_log"
      		 
      	}
      		 
      ]
