+<para>If you decided to compile your keymap file directly into the kernel
+back at the end of chapter 6, then you strictly speaking don't need to run
+this loadkeys script, since the kernel has already setup the keymap for
+you. You can still run it if you want, it isn't going to hurt you. It could
+even be beneficial to keep it in case you run a lot of different kernels
+and don't remember or want to compile the keymap into every kernel you lay
+your hands on.</para>
