    <title>Installation of efivar</title>

    <para>
      First, fix an issue in Makefile causing the package to be rebuilt
      during installation:
    </para>

<screen><userinput>sed '/prep :/a\\ttouch prep' -i src/Makefile</userinput></screen>

    <para>
      Now adapt this package for a change in glibc-2.36:
    </para>

<screen><userinput>sed '/sys\/mount\.h/d' -i src/util.h
sed '/unistd\.h/a#include &lt;sys/mount.h&gt;' -i src/gpt.c src/linux.c</userinput></screen>

    <para>
      If building this package on a 32-bit system, apply a patch:
    </para>

<screen><userinput>[ $(getconf LONG_BIT) = 64 ] || patch -Np1 -i ../efivar-&efivar-version;-i686-1.patch</userinput></screen>

    <para>
      Build <application>efivar</application> with the following commands:
    </para>

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

    <para>
      The test suite of this package is dangerous.  Running it may trigger
      firmware bugs and make your system unusable without using some special
      hardware to reprogram the firmware.
    </para>

    <para>
      Now, as the <systemitem class="username">root</systemitem> user:
    </para>

<screen role="root"><userinput>make install LIBDIR=/usr/lib</userinput></screen>

  <sect2 role="commands">
    <title>Command Explanations</title>

    <para>
      <parameter>LIBDIR=/usr/lib</parameter>:
      This option overrides the default library directory of the package
      (<filename class="directory">/usr/lib64</filename>, which is not used
