With this in mind, I'm sending the following patch for grub2 upstream. It
implements something analogous to this for UEFI systems. With this, a
change to how we generate grub2 configuration files (just adding a call),
and small amount of userland hacking, we can effectively cause the bootloader
to use a large timeout when the previous boot has failed.
