407 | If you specify grub, it will assume grub version 1 | |
408 | and will search in /boot/grub/menu.lst for the title \$GRUB_MENU | |
409 | and select that target to reboot to the kernel. If this is not | |
410 | your setup, then specify "script" and have a command or script | |
411 | specified in REBOOT_SCRIPT to boot to the target. | |
412 | ||
413 | The entry in /boot/grub/menu.lst must be entered in manually. | |
414 | The test will not modify that file. | |
a15ba913 SR |
415 | |
416 | If you specify grub2, then you also need to specify both \$GRUB_MENU | |
417 | and \$GRUB_FILE. | |
7786954c SR |
418 | |
419 | If you specify syslinux, then you may use SYSLINUX to define the syslinux | |
420 | command (defaults to extlinux), and SYSLINUX_PATH to specify the path to | |
421 | the syslinux install (defaults to /boot/extlinux). But you have to specify | |
422 | SYSLINUX_LABEL to define the label to boot to for the test kernel. | |

428 | |
429 | Note, ktest.pl will not update the grub menu.lst, you need to | |
430 | manually add an option for the test. ktest.pl will search | |
431 | the grub menu.lst for this option to find what kernel to | |
432 | reboot into. | |
433 | ||
434 | For example, if in the /boot/grub/menu.lst the test kernel title has: | |
435 | title Test Kernel | |
436 | kernel vmlinuz-test | |
437 | GRUB_MENU = Test Kernel | |
a15ba913 SR |
438 | |
439 | For grub2, a search of \$GRUB_FILE is performed for the lines | |
440 | that begin with "menuentry". It will not detect submenus. The | |
441 | menu must be a non-nested menu. Add the quotes used in the menu | |
442 | to guarantee your selection, as the first menuentry with the content | |
443 | of \$GRUB_MENU that is found will be used. | |
