I was prompted by Update Manager today to download/install some updates, including a new Linux kernel image. I was prompted twice asking if I wanted to create a /grub/...menu.lst file, because it was missing. That was old grub stuff. New grub2 doesn't use that. So, something is strange about these updates. I answered the question "no" both times. Then some updates failed, as reported by update-manager.
