<para>
Controls whether or not the image recipe specified by
<link linkend='var-INITRAMFS_IMAGE'><filename>INITRAMFS_IMAGE</filename></link>
is run through an extra pass during kernel compilation
in order to build a single binary that contains both the
kernel image and the initial RAM disk (initramfs).
The combined binary is deposited into the
<filename>tmp/deploy</filename> directory, which is part
of the
<ulink url='&YOCTO_DOCS_DEV_URL;#build-directory'>Build Directory</ulink>.
</para>
<para>
Setting the variable to "1" in a configuration file causes
the OpenEmbedded build system to make the extra pass during
kernel compilation:
<literallayout class='monospaced'>
INITRAMFS_IMAGE_BUNDLE = "1"
</literallayout>
<note>
You must set the
<filename>INITRAMFS_IMAGE_BUNDLE</filename> variable in
a configuration file.
You cannot set the variable in a recipe file.
