-<para><userinput>ln -s /static/bin/pwd /bin/pwd</userinput>: In the kernel
-source, the path to the <filename>pwd</filename> program is hard-wired as
-<filename>/bin/pwd</filename>, so we create a temporary symlink to account
-for that. At the end we remove it again.</para>
-
-<para><userinput>make mrproper</userinput>: This ensures that the kernel
-tree is absolutely clean. The kernel team recommends that this command be
-issued prior to <emphasis>each</emphasis> kernel compilation. You
-shouldn't rely on the source tree being clean after untarring.</para>
-
-<para><userinput>make include/linux/version.h</userinput> and
-<userinput>make symlinks</userinput>: This creates the
-<filename>include/linux/version.h</filename> file and the platform-specific
-<filename class="symlink">include/asm</filename> symlink.</para>
-
-<para><userinput>cp -HR include/asm /usr/include</userinput> and
-<userinput>cp -R include/asm-generic /usr/include</userinput>:
-These commands copy the platform-specific assembler kernel header files to
-<filename class="directory">/usr/include/asm</filename> and <filename
-class="directory">/usr/include/asm-generic</filename>.</para>
-
-<para><userinput>cp -R include/linux /usr/include</userinput>:
-This command copies the cross-platform kernel header files to
-<filename>/usr/include</filename>.</para>
-
-<para><userinput>touch /usr/include/linux/autoconf.h</userinput>: This
-creates an empty <filename>autoconf.h</filename> file.  As we do not yet
-configure the kernel, we have to create this file ourselves for those few
-kernel header files that make use of it, to avoid compilation failures.</para>
