 or at least every time you need an update of the upstream source tree.
 
+\section{Accessing stable releases}
+
+Having the Linux kernel development sources is great, but when you are 
+creating products, you prefer to avoid working with target that moves
+every day.
+
+That's why we need to use the {\em stable} releases of the Linux
+kernel.
+
+Fortunately, with \code{git}, you won't have to clone an entire source
+tree again. All you need to do is add a reference to a {\em remote}
+tree, and fetch only the commits which are specific to that remote tree.
+
+\begin{verbatim}
+git remote add stable git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
+git fetch stable
+\end{verbatim}
+
+This still represents about 80 MB worth of git objects to download, as
+the time of this writing (as of 3.11.1).
+
+We will choose a particular stable version in the next labs.
+
 Now, let's continue the lectures. This will leave time for the commands
 that you typed to complete their execution (if needed).
