| The GRUB2 payload reads its runtime configuration file from etc/grub.cfg |

| into a rescue shell. |

| This configuration may need to be coreboot specific. |

| configuration file into CBFS as `etc/grub.cfg` automatically. |
| |
| You will be able to specify the path of the configuration file later. |
