+Kernel Development FAQ
+**********************
+
+Common Questions and Solutions
+==============================
+
+The following lists some solutions for common questions.
+
+How do I use my own Linux kernel ``.config`` file?
+--------------------------------------------------
+
+Refer to the
+":ref:`kernel-dev/common:changing the configuration`"
+section for information.
+
+How do I create configuration fragments?
+----------------------------------------
+
+A: Refer to the
+":ref:`kernel-dev/common:creating configuration fragments`"
+section for information.
+
+How do I use my own Linux kernel sources?
+-----------------------------------------
+
+Refer to the
+":ref:`kernel-dev/common:working with your own sources`"
+section for information.
+
+How do I install/not-install the kernel image on the rootfs?
+------------------------------------------------------------
+
+The kernel image (e.g. ``vmlinuz``) is provided by the
+``kernel-image`` package. Image recipes depend on ``kernel-base``. To
+specify whether or not the kernel image is installed in the generated
+root filesystem, override ``RDEPENDS_${KERNEL_PACKAGE_NAME}-base`` to include or not
+include "kernel-image". See the
+":ref:`dev-manual/common-tasks:using .bbappend files in your layer`"
+section in the
+Yocto Project Development Tasks Manual for information on how to use an
+append file to override metadata.
+
+How do I install a specific kernel module?
+------------------------------------------
+
+Linux kernel modules are packaged individually. To ensure a
+specific kernel module is included in an image, include it in the
+appropriate machine :term:`RRECOMMENDS` variable.
+These other variables are useful for installing specific modules:
+- :term:`MACHINE_ESSENTIAL_EXTRA_RDEPENDS`
+- :term:`MACHINE_ESSENTIAL_EXTRA_RRECOMMENDS`
+- :term:`MACHINE_EXTRA_RDEPENDS`
+- :term:`MACHINE_EXTRA_RRECOMMENDS`
+
+For example, set the following in the ``qemux86.conf`` file to include
+the ``ab123`` kernel modules with images built for the ``qemux86``
+machine:
+::
+
+ MACHINE_EXTRA_RRECOMMENDS += "kernel-module-ab123"
+
+For more information, see the
+":ref:`kernel-dev/common:incorporating out-of-tree modules`" section.
+
+How do I change the Linux kernel command line?
+----------------------------------------------
+
+The Linux kernel command line is
+typically specified in the machine config using the ``APPEND`` variable.
+For example, you can add some helpful debug information doing the
+following:
+::
+
+ APPEND += "printk.time=y initcall_debug debug"
+
