<p>The base system of the <ahref="/cryptobox?action=doc&page=CryptoBox">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&weblang=en">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?action=doc&page=CryptoBox&weblang=en">CryptoBox</a> is compiled statically. If you want to change it, you could follow this steps: </p>
<li><p>change the kernel in the <em>unpackdebs</em> setting in <em>dfs-cbox.conf</em> (see <ahref="/cryptobox?action=doc&page=CryptoBoxDevCustomBuild&weblang=en">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>.
