 {Root filesystem construction}
-{Objectives:}
+{Objectives:
+  \begin{itemize}
+  \item Explore the build output
+  \item Customize the root filesystem using a {\em rootfs overlay}
+  \item Customize the kernel with patches and additional configuration
+    options
+  \item Add more packages
+  \item Use {\em defconfig} files and {\em out of tree} build
+  \end{itemize}
+}
 
 \section{Explore the build output}
 
+Now that we have discussed during the lectures the organization of the
+Buildroot {\em output} tree, take some time to look inside
+\code{output/} for the different build artefacts. And especially:
+
+\begin{itemize}
+
+\item Identify where the cross-compiler has been installed.
+
+\item Identify where the source code for the different components has
+  been extracted, and which packages have been built.
+
+\item Identify where the target root filesystem has been created, and
+  read the \code{THIS_IS_NOT_YOUR_ROOT_FILESYSTEM} file.
+
+\item See where the \code{staging} symbolic link is pointing to.
+
+\end{itemize}
+
 \section{Configure the network on your host}
 
 In the next sections of this lab, we will want to interact with the
