+Root filesystem with Buildroot
+------------------------------
+
+This challenge is derived from our "Buildroot" lab. Look
+at this lab for further instructions.
+
+The goal is to add rebuild the root filesystem with an audio player
+and play the sample sound.
+
+The command to run QEMU is the same. The emulated hardware already
+has sound support.
+
+Known issue: the sample.ogg sample will play in a weird way
+in QEMU (investigating, but no solution found yet). To have a
+correct result, add support for the "aplay"
+command in alsa-utils, and play the same in WAV format:
