402 | and will search in /boot/grub/menu.lst for the title \$GRUB_MENU | |
403 | and select that target to reboot to the kernel. If this is not | |
404 | your setup, then specify "script" and have a command or script | |
405 | specified in REBOOT_SCRIPT to boot to the target. | |
406 | ||
407 | The entry in /boot/grub/menu.lst must be entered in manually. | |
408 | The test will not modify that file. | |
a15ba913 SR |
409 | |
410 | If you specify grub2, then you also need to specify both \$GRUB_MENU | |
411 | and \$GRUB_FILE. | |
7786954c SR |

413 | If you specify syslinux, then you may use SYSLINUX to define the syslinux | |
414 | command (defaults to extlinux), and SYSLINUX_PATH to specify the path to | |
415 | the syslinux install (defaults to /boot/extlinux). But you have to specify | |
416 | SYSLINUX_LABEL to define the label to boot to for the test kernel. | |

425 | the grub menu.lst for this option to find what kernel to | |

429 | title Test Kernel | |
430 | kernel vmlinuz-test | |
431 | GRUB_MENU = Test Kernel | |
a15ba913 SR |
432 | |
433 | For grub2, a search of \$GRUB_FILE is performed for the lines | |
434 | that begin with "menuentry". It will not detect submenus. The | |
435 | menu must be a non-nested menu. Add the quotes used in the menu | |
436 | to guarantee your selection, as the first menuentry with the content | |
