# 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.
