It controls whether to include the 'deb-src' lines in image's source.list. Currently they are always included. This patch changes this behavior by not including them by default; the user must set this new config to true in order to include them. This saves a bit of bandwidth in default installations. Also, the use of src packages is not so usual in ordinary installations.
