    <para>The Module-Init-Tools source tarball doesn't contain generated
    man pages.  Apply the following patch so that no attempt to generate the
    man pages is made (such attempts will fail due to a lack of necessary tools
    in the LFS system):</para>

    <para>The testsuite of this package is geared towards the needs of its
    Maintainer. The command <command>make check</command> builds a specially
    wrapped version of modprobe which is useless for normal operation. To run
    this (about 0.2 SBU), issue the following commands (note that the
    <command>make clean</command> command is required to clean up the source
    tree before recompiling for normal use):</para>
