+# grub2
+#
+# TODO
+#
+#  * grub2's autogen uses ruby, which isn't part of the core Debian
+#    installation. So either decide it is a requirement for Buildroot,
+#    or build it for the host.
+#
+#  * improve the installation procedure. For the moment, it just
+#    installs everything in $(TARGET_DIR).
