    <title>Images</title>

    <para>
        The OpenEmbedded build system provides several example
        images to satisfy different needs.
        When you issue the <filename>bitbake</filename> command you provide a “top-level” recipe
        that essentially begins the build for the type of image you want.
    </para>

    <note>
        Building an image without GNU General Public License Version 3 (GPLv3),
        GNU Lesser General Public License Version 3 (LGPLv3), and the
        GNU Affero General Public License Version 3 (AGPL-3.0) components
        is only supported for minimal and base images.
        Furthermore, if you are going to build an image using non-GPLv3 and
        similarly licensed components, you must make the following changes in
        the <filename>local.conf</filename> file before using the BitBake
        command to build the minimal or base image:
        <literallayout class='monospaced'>
     1. Comment out the EXTRA_IMAGE_FEATURES line
     2. Set INCOMPATIBLE_LICENSE = "GPL-3.0 LGPL-3.0 AGPL-3.0"
        </literallayout>
    </note>

    <para>
        From within the <filename>poky</filename> Git repository, you can use
        the following command to display the list of directories within the
        <link linkend='source-directory'>Source Directory</link>
        that contain image recipe files:
        <literallayout class='monospaced'>
     $ ls meta*/recipes*/images/*.bb
        </literallayout>
    </para>

    <para>
        Following is a list of supported recipes:

                You can boot and run the image using either the

                enables LSB compliance (e.g. <filename>poky-lsb</filename>).
                If you build <filename>core-image-lsb</filename> without that
