Yeah :) > So that’s where we are. Thoughts on how to address it? https://www.gnu.org/software/grub/manual/grub.html#Making-a-GRUB-bootable-CD_002dROM says: >...grub-mkrescue >This produces a file named grub.iso, which then can be burned into a CD (or a >DVD), or written to a USB mass storage device. >The root device will be set up appropriately on entering your grub.cfg >configuration file, so you can refer to file names on the CD without needing >to use an explicit device name. This makes it easier to produce rescue images >that will work on both optical drives and USB mass storage devices. So... just leave the entire "search" instruction off if it's created by grub-mkrescue ? That's how one could interpret thir "root device" sentence...
