404 | $config_help{"REBOOT_TYPE"} = << "EOF" | |
405 | Way to reboot the box to the test kernel. | |
7786954c | 406 | Only valid options so far are "grub", "grub2", "syslinux", and "script". |
8d1491ba SR |
407 | |
408 | If you specify grub, it will assume grub version 1 | |
409 | and will search in /boot/grub/menu.lst for the title \$GRUB_MENU | |
410 | and select that target to reboot to the kernel. If this is not | |
411 | your setup, then specify "script" and have a command or script | |
412 | specified in REBOOT_SCRIPT to boot to the target. | |
413 | ||
414 | The entry in /boot/grub/menu.lst must be entered in manually. | |
415 | The test will not modify that file. | |
a15ba913 SR |
416 | |
417 | If you specify grub2, then you also need to specify both \$GRUB_MENU | |
418 | and \$GRUB_FILE. | |
7786954c SR |
419 | |
420 | If you specify syslinux, then you may use SYSLINUX to define the syslinux | |
421 | command (defaults to extlinux), and SYSLINUX_PATH to specify the path to | |
422 | the syslinux install (defaults to /boot/extlinux). But you have to specify | |
423 | SYSLINUX_LABEL to define the label to boot to for the test kernel. | |
8d1491ba SR |
424 | EOF |
425 | ; | |
426 | $config_help{"GRUB_MENU"} = << "EOF" | |

a15ba913 | 428 | (Only mandatory if REBOOT_TYPE = grub or grub2) |
8d1491ba SR |
429 | |
430 | Note, ktest.pl will not update the grub menu.lst, you need to | |
431 | manually add an option for the test. ktest.pl will search | |
432 | the grub menu.lst for this option to find what kernel to | |
433 | reboot into. | |
434 | ||
435 | For example, if in the /boot/grub/menu.lst the test kernel title has: | |
436 | title Test Kernel | |
437 | kernel vmlinuz-test | |
438 | GRUB_MENU = Test Kernel | |
a15ba913 SR |
439 | |
440 | For grub2, a search of \$GRUB_FILE is performed for the lines | |
441 | that begin with "menuentry". It will not detect submenus. The | |
442 | menu must be a non-nested menu. Add the quotes used in the menu | |
443 | to guarantee your selection, as the first menuentry with the content | |
444 | of \$GRUB_MENU that is found will be used. | |
445 | EOF | |
446 | ; | |
447 | $config_help{"GRUB_FILE"} = << "EOF" | |
448 | If grub2 is used, the full path for the grub.cfg file is placed | |
449 | here. Use something like /boot/grub2/grub.cfg to search. | |

7786954c SR |
452 | $config_help{"SYSLINUX_LABEL"} = << "EOF" |
453 | If syslinux is used, the label that boots the target kernel must | |
