        Dependencies:   NA
        Steps:          1. Build kernel with bitbake.
                        2. Save the config file generated.
                        3. Clean the environment.
                        4. Use `devtool modify virtual/kernel` to validate following:
                           4.1 The source is checked out correctly.
                           4.2 The resulting configuration is the same as
                               what was get on step 2.
                           4.3 The Kernel can be build correctly.
                           4.4 Changes made on the source are reflected on the
                               subsequent builds.
                           4.5 Changes on the configuration are reflected on the
                               subsequent builds
         Expected:       devtool modify is able to checkout the source of the kernel
                         and modification to the source and configurations are reflected
                         when building the kernel.
