224 | If you specify grub, it will assume grub version 1 | |
225 | and will search in /boot/grub/menu.lst for the title \$GRUB_MENU | |
226 | and select that target to reboot to the kernel. If this is not | |
227 | your setup, then specify "script" and have a command or script | |
228 | specified in REBOOT_SCRIPT to boot to the target. | |
229 | ||

237 | ||
238 | Note, ktest.pl will not update the grub menu.lst, you need to | |
239 | manually add an option for the test. ktest.pl will search | |
240 | the grub menu.lst for this option to find what kernel to | |
241 | reboot into. | |
242 | ||
243 | For example, if in the /boot/grub/menu.lst the test kernel title has: | |
244 | title Test Kernel | |
245 | kernel vmlinuz-test | |
246 | GRUB_MENU = Test Kernel | |
