The base system of the <a href="/cryptobox?action=doc&page=CryptoBox">CryptoBox</a> Live-CD is created by <a class="ext-link" title="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=dfsbuild" href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=dfsbuild&weblang=en">dfsbuild</a>.

It is recommended to use some kind of caching tool for the retrieval of the debian packages (e.g.: <a class="ext-link" title="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=apt-cacher" href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=apt-cacher">apt-cacher</a>, <a class="ext-link" title="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=apt-proxy" href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=apt-proxy">apt-proxy</a> or <a class="ext-link" title="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=approx" href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=approx">approx</a>). This saves a lot of bandwidth and time.

The documentation for <a class="ext-link" title="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=dfsbuild" href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;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 <a href="/trac/cryptobox/browser/trunk/scripts/cbox-build.sh">cbox-build</a>. However the following links may help you for specific problems:

<ul><li><a class="ext-link" title="http://www.debian-administration.org/articles/125" href="http://www.debian-administration.org/articles/125">Debian Administration: Building Debian CD-ROMS Part 1 - dfsbuild</a>

</li></ul><h2 id="thekernel">the kernel</h2>
<p>
The linux kernel for the <a href="/cryptobox?action=doc&page=CryptoBox&weblang=en">CryptoBox</a> is compiled statically. If you want to change it, you could follow this steps:
</p>
<ol><li>get the sources: <tt>apt-get install kernel-tree-2.6.11</tt> (or the version of your choice)
</li><li>copy the exisiting config file <i>kernel/config-2.6.11</i> as <i>.config</i> into your kernel source directory
</li><li>build the debian kernel package <tt>make-kpkg --revision=1.dfs --rootcmd=fakeroot kernel_image</tt>
</li><li>change the kernel in the <i>unpackdebs</i> setting in <a href="/trac/cryptobox/browser/trunk/etc-defaults.d/dfs-cbox.conf">dfs-cbox.conf</a> (see <a href="/cryptobox?action=doc&page=CryptoBoxDevCustomBuild&weblang=en">CryptoBoxDevCustomBuild</a> for details)
</li></ol><p>
See <a title="" href="/trac/cryptobox/browser/trunk/hints/kernel-build.txt">source:trunk/hints/kernel-build.txt</a> for more details.

<h2 id="qemu">qemu</h2>
<p>
<a class="ext-link" title="http://fabrice.bellard.free.fr/qemu/" 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>
We tried some other LiveCDs before we decided to use <a class="ext-link" title="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=dfsbuild" href="http://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&amp;subword=0&amp;version=all&amp;release=all&amp;keywords=dfsbuild">dfsbuild</a>. The following pages describe their advantages and disadvantages as the base system for the <a href="/cryptobox?action=doc&page=CryptoBox&weblang=en">CryptoBox</a>:
