| The box is expected to have ssh on normal bootup, provide the user |

| $config_help{"BUILD_DIR"} = << "EOF" |
| The directory that contains the Linux source code (full path). |

| |
| If you specify grub, it will assume grub version 1 |
| and will search in /boot/grub/menu.lst for the title \$GRUB_MENU |
| and select that target to reboot to the kernel. If this is not |
| your setup, then specify "script" and have a command or script |
| specified in REBOOT_SCRIPT to boot to the target. |

| The grub title name for the test kernel to boot |
| (Only mandatory if REBOOT_TYPE = grub) |
| |
| Note, ktest.pl will not update the grub menu.lst, you need to |
| manually add an option for the test. ktest.pl will search |
| the grub menu.lst for this option to find what kernel to |
| reboot into. |
| |
| For example, if in the /boot/grub/menu.lst the test kernel title has: |
| title Test Kernel |
| kernel vmlinuz-test |
| GRUB_MENU = Test Kernel |
