401 | and will search in /boot/grub/menu.lst for the title \$GRUB_MENU | |
402 | and select that target to reboot to the kernel. If this is not | |

404 | specified in REBOOT_SCRIPT to boot to the target. | |
405 | ||
406 | The entry in /boot/grub/menu.lst must be entered in manually. | |
407 | The test will not modify that file. | |

409 | If you specify grub2, then you also need to specify both \$GRUB_MENU | |

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

a15ba913 SR |
431 | |
432 | For grub2, a search of \$GRUB_FILE is performed for the lines | |
433 | that begin with "menuentry". It will not detect submenus. The | |
434 | menu must be a non-nested menu. Add the quotes used in the menu | |
