+# XXX: we need to review menu.lst vs grub.conf handling. We've been converting
+# all systems to grub.conf (and symlinking menu.lst to grub.conf), but
+# we never updated any of the source code (it still all wants menu.lst),
+# and there is no indication that upstream is making the transition.
+
+# If you need to roll a new grub-static distfile, here is how.
