-I entered runqemu qemux86 and it fires upthis fires up the emulator and uses the
-image and filesystem in the build area created in the previous section.
-
-Then I copied over a pre-created and formated 5.2MB VFAT file named vfat.img.
-I did this with scp vfat.img root@192.168.7.2:
-The file is in the root directory.
-I had to do this because the mkfs.vfat vfat.img command does not work.
-mkfs is not recognized in the qemu terminal session.
-
-when I try mount -o loop -t vfat vfat.img mnt/ I get the error
-mount: can't set up loop device: No space left on device.
-This error is because the loop module is not currently in the kernel image.
-However, this module is available in the 
-build area in the tarball modules-2.6.37.6-yocto-starndard+-20-qemux86.tgz.
-You can add this to the kernel image by adding the 
-IMAGE_INSTALL += " kernel-module-loop" statement at the top of the local.conf
-file in the build area and then rebuilding the kernel using bitbake.
-It should just build whatever is necessary and not go through an entire build again.

-                The <filename>menuconfig</filename> tool provides an interactive method with which
-                to set kernel configurations.
-                In order to use <filename>menuconfig</filename> from within the BitBake environment
-                you need to source an environment setup script.
-                This script is located in the local Yocto Project file structure and is called

-                Once menuconfig fires up you see all kinds of categories that you can interactively
-                investigate.
-                If they have an "M" in it then the feature is "modularized".
-                I guess that means that means that it needs to be manually linked in when the 
-                kernel is booted??? (Not sure).
-                If they have an "*" then the feature is automatically part of the kernel.]

-                So the tmp/work/ area was created in poky and there is a .config file in there and
-                a .config.old file.  
-                The old one must have been created when I exited from menuconfig after poking around 
-                a bit.
-                Nope - appears to just be created automatically.

-                A good practice is to first determine what configurations you have for the kernel.
-                You can see the results by looking in the .config file in the build/tmp/work/qemux86-poky-linux area
-                of the local YP files. 
-                There is a directory named linux-yocto-2.6.37* in the directory.
-                In that directory is a directory named linux-qemux86-standard-build.
-                In that directory you will find a file named .config that is the configuration file
-                for the kernel that will be used when you build the kernel.
-                You can open that file up and examine it. 
-                If you do a search for "VFAT" you will see that that particular configuration is not 
-                enabled for the kernel.
-                This means that you cannot print a VFAT text file, or for that matter, even mount one
-                from the image if you were to build it at this point.
-            </para>

-            <para>
-                You can prove the point by actually trying it at this point.

-EXTRA STUFF I MIGHT NEED BUT NOW SURE RIGHT NOW.
-
-In the standard layer structure you have several areas that you need to examine or 
-                    modify.
-                    For this example the layer contains four areas:
-                    <itemizedlist>
-                        <listitem><para><emphasis><filename>conf</filename></emphasis> - Contains the 
-                        <filename>layer.conf</filename> that identifies the location of the recipe files. 
-                        </para></listitem>
-                        <listitem><para><emphasis><filename>images</filename></emphasis> - Contains the 
-                        image recipe file. 
-                        This recipe includes the base image you will be using and specifies other 
-                        packages the image might need.</para></listitem>
-                        <listitem><para><emphasis><filename>recipes-bsp</filename></emphasis> - Contains 
-                        recipes specific to the hardware for which you are developing the kernel.
-                        </para></listitem>
-                        <listitem><para><emphasis><filename>recipes-kernel</filename></emphasis> - Contains the 
-                        "append" files that add information to the main recipe kernel.  
-                        </para></listitem>
-                    </itemizedlist>
-                </para>
-
-                <para>
-                    Let's take a look at the <filename>layer.conf</filename> in the 
-                    <filename>conf</filename> directory first.
-                    This configuration file enables the Yocto Project build system to locate and 
-                    use the information in your new layer.
-                </para>
-
-                <para>
-                    The variable <filename>BBPATH</filename> needs to include the path to your layer
-                    as follows:
-                    <literallayout class='monospaced'>
-     BBPATH := "${BBPATH}:${LAYERDIR}"
-                    </literallayout>
-                    And, the variable <filename>BBFILES</filename> needs to be modified to include your 
-                    recipe and append files:
-                    <literallayout class='monospaced'>
-     BBFILES := "${BBFILES} ${LAYERDIR}/images/*.bb \ 
-        ${LAYERDIR}/images/*.bbappend \
-        ${LAYERDIR}/recipes-*/*/*.bb \
-        ${LAYERDIR}/recipes-*/*/*.bbappend"
-                    </literallayout>
-                    Finally, you need to be sure to use your layer name in these variables at the 
-                    end of the file:
-                    <literallayout class='monospaced'>
-     BBFILE_COLLECTIONS += "elc"
-     BBFILE_PATTERN_elc := "^${LAYERDIR}/"
-     BBFILE_PRIORITY_elc = "9"
-                   </literallayout>
-                </para>
-
-                <para>
-                    The <filename>images</filename> directory contains an append file that helps 
-                    further define the image.
-                    In our example, the base image is <filename>core-image-minimal</filename>.  
-                    The image does, however, need some additional modules that we are using
-                    for this example.
-                    These modules support the amixer functionality.
-                    Here is the append file:
-                    <literallayout class='monospaced'>
-     require recipes-core/images/poky-image-minimal.bb

-                   While the focus of this example is not on the BSP, it is worth mentioning that the
-                   <filename>recipes-bsp</filename> directory has the recipes and append files for 
-                   features that the hardware requires. 
-                   In this example, there is a script and a recipe to support the 
-                   <filename>amixer</filename> functionality in QEMU.
-                   It is beyond the scope of this manual to go too deeply into the script.
-                   Suffice it to say that the script tests for the presence of the mixer, sets up 
-                   default mixer values, enables the mixer, unmutes master and then 
-                   sets the volume to 100.
