The configuration being used is copied from this package, so it
is easier to change it if needed.
@c again, maybe simplify this to a set of commands?
If you want to change the configuration, you can do so after the first
build iteration: change directory to @code{build/kernel}
and run @code{make menuconfig}. After making your choices, copy back
the file @code{.config} to
@code{patches/kernel/v2.6.39/linux-config-wrswitch} in this package.
You can also set @code{WRS_KERNEL_CONFIG} to the full pathname of
The configuration we use to build the kernel is not a patch but a plan
@code{.config} file, in the same directory as the patches, so you
can change it easily, if needed. As an alternative,
you can also set @code{WRS_KERNEL_CONFIG} to the full pathname of
your configuration file of choice. The file must be a copy of the
@code{.config} found in the main kernel directory,
(for example the one left after the @code{make menuconfig} step).
