-    <para>
-        In one of our previous releases (denzil), users noticed that booting
-        off of a live image and writing to disk was noticeably slower.
-        This included the boot itself, especially the first one, since first
-        boots tend to do a significant amount of writing due to certain
-        post-install scripts.
-    </para>
-
-    <para>
-        The problem (and solution) was discovered by using the Yocto tracing
-        tools, in this case 'perf stat', 'perf script', 'perf record'
-        and 'perf report'.
