+ If you specify grub, it will assume grub version 1
+ and will search in /boot/grub/menu.lst for the title \$GRUB_MENU
+ and select that target to reboot to the kernel. If this is not
+ your setup, then specify "script" and have a command or script
+ specified in REBOOT_SCRIPT to boot to the target.
+
+ The entry in /boot/grub/menu.lst must be entered in manually.
+ The test will not modify that file.
+
+ If you specify grub2, then you also need to specify both \$GRUB_MENU
+ and \$GRUB_FILE.
+
+ If you specify grub2bls, then you also need to specify \$GRUB_MENU.
+
+ If you specify syslinux, then you may use SYSLINUX to define the syslinux
+ command (defaults to extlinux), and SYSLINUX_PATH to specify the path to
+ the syslinux install (defaults to /boot/extlinux). But you have to specify
+ SYSLINUX_LABEL to define the label to boot to for the test kernel.

+ (Only mandatory if REBOOT_TYPE = grub or grub2)

+ manually add an option for the test. ktest.pl will search
+ the grub menu.lst for this option to find what kernel to
+ reboot into.
+
+ For example, if in the /boot/grub/menu.lst the test kernel title has:
+ title Test Kernel
+ kernel vmlinuz-test
+ GRUB_MENU = Test Kernel
+
+ For grub2, a search of \$GRUB_FILE is performed for the lines
+ that begin with "menuentry". It will not detect submenus. The
+ menu must be a non-nested menu. Add the quotes used in the menu
+ to guarantee your selection, as the first menuentry with the content
+ of \$GRUB_MENU that is found will be used.
+
+ For grub2bls, \$GRUB_MENU is searched on the result of \$GRUB_BLS_GET
+ command for the lines that begin with "title".
