<glossentry id='var-LINUX_VERSION_EXTENSION'><glossterm>LINUX_VERSION_EXTENSION</glossterm>
<glossdef>
<para>A string extension compiled into the name of the
Linux kernel built with the OpenEmbedded build system.
You define this variable in the kernel recipe.
For example, the <filename>linux-yocto-custom.bb</filename>
kernel recipe found in
<filename>meta-skeleton/recipes-kernel/linux</filename>
defines the variable as follows:
<literallayout class='monospaced'>
LINUX_VERSION_EXTENSION ?= "-custom"
</literallayout>
Defining this variable essentially sets the
Linux kernel configuration item
<filename>CONFIG_LOCALVERSION</filename>, which is visible
through the <filename>uname</filename> command.
Here is an example that shows the extension assuming it
was set as previously shown:
<literallayout class='monospaced'>
$ uname -r
3.7.0-rc8-custom
</literallayout>
