+  \begin{itemize}
+    \item A distro layer is used to provides policy configurations for
+      a custom distribution.
+    \item It is a best practice to separate the distro layer from the
+      custom layers you may create and use.
+    \item It often contains:
+      \begin{itemize}
+        \item Configuration files.
+        \item Specific classes.
+        \item Distribution specific recipes: initialization scripts,
+          splash screen packages\dots
