<title>Installation of Module-Init-Tools</title>

<para>Module-Init-Tools attempts to rewrite its
<filename>modprobe.conf</filename> man page during the build process. This is
unnecessary and also relies on <command>docbook2man</command> &mdash; which is not
installed in LFS. Run the following command to avoid this:</para>

<screen><userinput>touch modprobe.conf.5</userinput></screen>

<para>Prepare Module-Init-Tools for compilation:</para>

<screen><userinput>./configure --prefix="" --enable-zlib</userinput></screen>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>To test the results, issue:
<userinput>make check</userinput>.</para>

<para>Install the package:</para>

<screen><userinput>make install</userinput></screen>
