<p>The base system of the <ahref="CryptoBox.html">CryptoBox</a> Live-CD is created by <aclass="interwiki"title="DebianPackage"href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&subword=1&version=all&release=all&keywords=dfsbuild">dfsbuild</a>. </p>
<p>It is recommended to use some kind of caching tool for the retrieval of the debian packages (e.g.: <aclass="interwiki"title="DebianPackage"href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&subword=1&version=all&release=all&keywords=apt-cacher">apt-cacher</a> or <aclass="interwiki"title="DebianPackage"href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&subword=1&version=all&release=all&keywords=apt-proxy">apt-proxy</a>). This saves a lot of bandwidth and time. </p>
<p>The documentation for <aclass="interwiki"title="DebianPackage"href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&subword=1&version=all&release=all&keywords=dfsbuild">dfsbuild</a> is sparse. But it is quite unlikely, that you will get in direct contact with it, as it is wrapped by <em>cbox-build</em>. However the following links may help you for specific problems: </p>

<p>The linux kernel for the <ahref="CryptoBox.html">CryptoBox</a> is compiled statically. If you want to change it, you could follow this steps: </p>
<oltype="1">
<li><p>get the sources: <tt>apt-get install kernel-tree-2.6.11</tt> (or the version of your choice) </p>
</li>
<li><p>copy the exisiting config file <em>kernel/config-2.6.11</em> as <em>.config</em> into your kernel source directory </p>
</li>
<li><p>build the debian kernel package <tt>make-kpkg --revision=1.dfs --rootcmd=fakeroot kernel_image</tt></p>
</li>
<li><p>change the kernel in the <em>unpackdebs</em> setting in <em>dfs-cbox.conf</em> (see <ahref="CryptoBoxDevCustomBuild.html">CryptoBoxDevCustomBuild</a> for details) </p>
<p><aclass="external"href="http://fabrice.bellard.free.fr/qemu/">Qemu</a> is a portable system emulator. It is a convenient tool to ease the development workflow, as you do not need to burn LiveCDs for testing. </p>
<p>We tried some other LiveCDs before we decided to use <aclass="interwiki"title="DebianPackage"href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&subword=1&version=all&release=all&keywords=dfsbuild">dfsbuild</a>. The following pages describe their advantages and disadvantages as the base system for the <ahref="CryptoBox.html">CryptoBox</a>: </p>
