To prevent one or several operating systems from being booted from the boot menu,
add the entry lock to every section in menu.lst that should not be bootable
without entering a password. For example:
title linux
kernel (hd0,4)/vmlinuz root=/dev/sda7 vga=791
initrd (hd0,4)/initrd
lock
After rebooting the system and selecting the Linux entry from the boot menu, the
following error message is displayed:
Error 32: Must be authenticated
Press Enter to enter the menu. Then press P to get a password prompt. After entering
the password and pressing Enter, the selected operating system (Linux in this case)
should boot.
9.2 Conguring the Boot Loader with
YaST
The easiest way to congure the boot loader in your openSUSE system is to use the
YaST module. In the YaST Control Center, select System > Boot Loader. As in Fig-
ure 9.1, “Boot Loader Settings” (page 167), this shows the current boot loader congu-
ration of your system and allows you to make changes.
