+  \frametitle{Root filesystem organization}
+  \begin{itemize}
+  \item The organization of a Linux root filesystem in terms of
+    directories is well-defined by the {\bf Filesystem Hierarchy
+      Standard}
+  \item \url{http://www.linuxfoundation.org/collaborate/workgroups/lsb/fhs}
+  \item Most Linux systems conform to this specification
+    \begin{itemize}
+    \item Applications expect this organization
+    \item It makes it easier for developers and users as the
+      filesystem organization is similar in all systems
+    \end{itemize}
+  \end{itemize}
+  \frametitle{Important directories (1)}
+  \begin{description}
+  \item[/bin] Basic programs
+  \item[/boot] Kernel image (only when the kernel is loaded from a
+    filesystem, not common on non-x86 architectures)
+  \item[/dev] Device files (covered later)
+  \item[/etc] System-wide configuration
+  \item[/home] Directory for the users home directories
+  \item[/lib] Basic libraries
+  \item[/media] Mount points for removable media
+  \item[/mnt] Mount points for static media
+  \item[/proc] Mount point for the proc virtual filesystem
+  \end{description}
+  \frametitle{Important directories (2)}
+  \begin{description}
+  \item[/root]Home directory of the root user
+  \item[/sbin]Basic system programs
+  \item[/sys]Mount point of the sysfs virtual filesystem
+  \item[/tmp]Temporary files
+  \item[/usr]
+    \begin{description}
+    \item[/usr/bin]Non-basic programs
+    \item[/usr/lib]Non-basic libraries
+    \item[/usr/sbin]Non-basic system programs
+    \end{description}
+  \item[/var] Variable data files. This includes spool directories and
+    files, administrative and logging data, and transient and
+    temporary files
+  \end{description}
+  \frametitle{Separation of programs and libraries}
+  \begin{itemize}
+  \item Basic programs are installed in \code{/bin} and \code{/sbin}
+    and basic libraries in \code{/lib}
+  \item All other programs are installed in \code{/usr/bin} and
+    \code{/usr/sbin} and all other libraries in \code{/usr/lib}
+  \item In the past, on Unix systems, \code{/usr} was very often
+    mounted over the network, through NFS
+  \item In order to allow the system to boot when the network was
+    down, some binaries and libraries are stored in \code{/bin},
+    \code{/sbin} and \code{/lib}
+  \item \code{/bin} and \code{/sbin} contain programs like \code{ls},
+    \code{ifconfig}, \code{cp}, \code{bash}, etc.
+  \item \code{/lib} contains the C library and sometimes a few other
+    basic libraries
+  \item All other programs and libraries are in \code{/usr}
+  \end{itemize}
