+\title{Rootfilesystem from scratch vs. Debian based system}
+\maketitle
+
+\subsection{Rootfilesystem from scratch}
+
+\subsubsection{Overview}
+\begin{frame}
+\frametitle{RFS from scratch}
+Advantage:
+\begin{itemize}
+\item smallest footprint
+\end{itemize}
+Disadvantages:
+\begin{itemize}
+\item manual dependency tracking
+\item hard to maintain (track bugs for each source)
+\end{itemize}
+Okay for systems that have less than 16 MB flash.
+\end{frame}
+
+\begin{frame}
+\frametitle{RFS from scratch}
+HOWTO: see app-devel/cross-devel section
+\end{frame}
+
+
+\subsection{Debian based system}
+
+\subsubsection{Overview}
+\begin{frame}
+\frametitle{Debian based system}
+Advantages
+\begin{itemize}
+\item Bugtracking is made by Debian
+\item Dependencytracking is made by Debian
+\item easy to add new packages
+\end{itemize}
+Disadvantages
+\begin{itemize}
+\item standard system is about 100 MB
+\end{itemize}
+\end{frame}
