# 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.
