    Familiarity with the GNU/Linux command line is a prerequisite anyway.

-  \begin{itemize}
-  \item Linux is a multi-user operating system
-    \begin{itemize}
-    \item The {\bf root user is the administrator}, and it can do
-      privileged operations such as: mounting filesystems, configuring
-      the network, creating device files, changing the system
-      configuration, installing or removing software
-    \item All {\bf other users are unprivileged}, and cannot perform
-      these administrator-level operations
-    \end{itemize}
-  \item On an Ubuntu system, it is not possible to log in as
-    \code{root}, only as a normal user.
-  \item The system has been configured so that the user account
-    created first is allowed to run privileged operations through a
-    program called \code{sudo}.\\
-    \begin{itemize}
-    \item Example: \code{sudo mount /dev/sda2 /mnt/disk}

-  \frametitle{Software packages}
-  \begin{itemize}
-  \item The distribution mechanism for software in GNU/Linux is
-    different from the one in Windows
-  \item Linux distributions provides a central and coherent way of
-    installing, updating and removing applications and libraries:
-    {\bf packages}
-  \item Packages contains the application or library files, and
-    associated meta-information, such as the version and the
-    dependencies
-    \begin{itemize}
-    \item \code{.deb} on Debian and Ubuntu, \code{.rpm} on Red Hat,
-      Fedora, openSUSE
-    \item Our practical labs will show you how to use the \code{apt}
-      command to install new packages on Debian based distros.
-    \end{itemize}
-  \item Packages are stored in {\bf repositories}, usually on HTTP or
-    HTTPS servers
-  \item You should only use packages from official repositories for your
-    distribution, unless strictly required.
-  \item Note: {\em Snap} and {\em Flatpak} offer new ways of packaging
-    applications in a self-contained way. See
-    \url{https://www.atechtown.com/flatpak-vs-snap/}.

-  \frametitle{Command line tips}
-  \begin{itemize}
-  \item Using the command line is mandatory for many operations needed
-    for embedded Linux development
-  \item It is a very powerful way of interacting with the system, with
-    which you can save a lot of time.
-  \item Some useful tips
-    \begin{itemize}
-    \item You can use several tabs in the Gnome Terminal
-    \item Remember that you can use relative paths (for example:
-      \code{../../linux}) in addition to absolute paths (for example:
-      \code{/home/user})
-    \item In a shell, hit \code{[Control] [r]}, then a keyword, will
-      search through the command history. Hit \code{[Control] [r]}
-      again to search backwards in the history
-    \item You can directly copy/paste paths from the file manager to
-      Gnome Terminal by drag-and-drop.
