177 | $config_help{"CONSOLE"} = << "EOF" | |

180 | If you use ttywatch server, something like the following would work. | |
181 | CONSOLE = nc -d localhost 3001 | |

193 | Way to reboot the box to the test kernel. | |
194 | Only valid options so far are "grub" and "script". | |
195 | ||
196 | If you specify grub, it will assume grub version 1 | |
197 | and will search in /boot/grub/menu.lst for the title \$GRUB_MENU | |
198 | and select that target to reboot to the kernel. If this is not | |
199 | your setup, then specify "script" and have a command or script | |
200 | specified in REBOOT_SCRIPT to boot to the target. | |
201 | ||
202 | The entry in /boot/grub/menu.lst must be entered in manually. | |
203 | The test will not modify that file. | |
204 | EOF | |

206 | $config_help{"GRUB_MENU"} = << "EOF" | |
207 | The grub title name for the test kernel to boot | |
208 | (Only mandatory if REBOOT_TYPE = grub) | |
209 | ||
210 | Note, ktest.pl will not update the grub menu.lst, you need to | |
211 | manually add an option for the test. ktest.pl will search | |
212 | the grub menu.lst for this option to find what kernel to | |
213 | reboot into. | |
214 | ||
215 | For example, if in the /boot/grub/menu.lst the test kernel title has: | |
216 | title Test Kernel | |
217 | kernel vmlinuz-test | |
