<para>The Kbd package contains key-table files and keyboard utilities.</para>

Diffutils, Flex, GCC, Gettext, Glibc, Grep, Gzip, M4, Make, Sed.</para>

<title>Installation of Kbd</title>
<para>By default some of Kbd's utilities (<command>setlogcons</command>,
<command>setvesablank</command> and <command>getunimap</command>) are
not installed. First enable the compilation of these utilities:</para>
<screen><userinput>patch -Np1 -i ../kbd-&kbd-version;-more-programs-1.patch</userinput></screen>
<para>Now prepare Kbd for compilation:</para>
<screen><userinput>./configure</userinput></screen>
<para>Compile the package:</para>
<screen><userinput>make</userinput></screen>
<para>Now install it:</para>

<para>Few things are more annoying than using Linux while a wrong keymap
for your keyboard is loaded. If you have a standard US keyboard, however, you
can skip this section, as the US keymap is the default as long as you don't
change it.</para>
<para>To change the default keymap, create the
<filename class="symlink">/usr/share/kbd/keymaps/defkeymap.map.gz</filename>
symlink by running the following command:</para>
<screen><userinput>ln -s path/to/keymap /usr/share/kbd/keymaps/defkeymap.map.gz</userinput></screen>
<para>Of course, replace <filename>path/to/keymap</filename> with the path and
name of your keyboard's map file. For example, if you have a Dutch keyboard,
you would use <filename>/usr/share/kbd/keymaps/i386/qwerty/nl.map.gz</filename>.</para>
<para>Another way to set your keyboard's layout is to compile the keymap
into the kernel. This ensures that your keyboard will always work as expected,
even when you boot into maintenance mode (by passing `init=/bin/sh' to the
kernel), as then the bootscript that normally sets up your keymap isn't run.</para>
<para>When in <xref linkend="chapter-bootable"/> you're ready to compile the
kernel, run the following command to patch the current default keymap into the
source (you will have to repeat this command whenever you unpack a new
kernel):</para>
<screen><userinput>loadkeys -m /usr/share/kbd/keymaps/defkeymap.map.gz > \
<replaceable>[unpacked sources dir]</replaceable>/linux-&linux-version;/drivers/char/defkeymap.c</userinput></screen>
