| $config_help{"SSH_USER"} = << "EOF" |
| The box is expected to have ssh on normal bootup, provide the user |
| (most likely root, since you need privileged operations) |

| The directory that the objects will be built (full path). |
| (can not be same as BUILD_DIR) |

| The place to put your image on the test machine. |
| EOF |

| $config_help{"POWER_CYCLE"} = << "EOF" |
| A script or command to reboot the box. |
| |
| Here is a digital loggers power switch example |
| POWER_CYCLE = wget --no-proxy -O /dev/null -q --auth-no-challenge 'http://admin:admin\@power/outlet?5=CCL' |

| Here is an example to reboot a virtual box on the current host |
| with the name "Guest". |
| POWER_CYCLE = virsh destroy Guest; sleep 5; virsh start Guest |
| EOF |

| $config_help{"CONSOLE"} = << "EOF" |
| The script or command that reads the console |
| |
| If you use ttywatch server, something like the following would work. |
| CONSOLE = nc -d localhost 3001 |
| |
| For a virtual machine with guest name "Guest". |

| Required version ending to differentiate the test |
| from other linux builds on the system. |
| EOF |
| ; |
| $config_help{"REBOOT_TYPE"} = << "EOF" |
| Way to reboot the box to the test kernel. |
| Only valid options so far are "grub" and "script". |
| |
| 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 entry in /boot/grub/menu.lst must be entered in manually. |
| The test will not modify that file. |
| EOF |
| ; |
| $config_help{"GRUB_MENU"} = << "EOF" |
| 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 |
| EOF |
| ; |
| $config_help{"REBOOT_SCRIPT"} = << "EOF" |
