<listitem><para>March 16th, 2002 [gerard]: Chapter 05 - Kernel: Shortened
the commands by removing <userinput>make mrproper</userinput>,
<userinput>make config</userinput>, and <userinput>make dep</userinput>.
Instead we just create the missing <filename>version.h</filename> and
<filename class="symlink">asm</filename> symlink and copy the headers to
<filename class="directory">$LFS/usr/include</filename>. We don't need the
kernel tree itself setup until chapter 8 where we would re-run the removed
commands anyways, so it's just a waste of time to do it in chapter
5.</para></listitem>

answers with the default answer to every question the config script asks
the user (it does this by simply doing the equivalent of hitting the
Enter key, thus accepting the default Y and N answers to the questions).
We're not configuring the real kernel here, we just need to have some sort
of configure file created so that we can run make dep next that will
create a few header files in <filename>include/linux</filename>, like
version.h, among others, that we will need to compile Glibc and other
packages later in chroot.</para>
<para><userinput>make dep:</userinput> make dep checks dependencies and sets
up the dependencies file. We don't really care about the dependency
checks, but what we do care about is that make dep creates those
aforementioned files in <filename>include/linux</filename> we will be
needing later on.</para>
