| # 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. |
