{{#-
  We set defaults to "off", and products should enable relevant ones depending on how the product configures grub.
   - /boot/loader/entries/* may not exist.
   - If they exist, they can reference variables defined in grubenv, or they can contain literal args
   - The grub cfg may either use those loader entries, or it can contain literal values as well
   - Kernel opts can be stored in /etc/default/grub so they are persistent between kernel upgrades
