On systems that have a UFS root, the active menu.lst file is typically located at /boot/grub/menu.lst. To locate the active GRUB menu, use the bootadm command with the list-menu option: # bootadm list-menu Determine if the system uses the GRUB boot loader. Procedure: # more /pool-name/boot/grub/menu.lst or # more /boot/grub/menu.lst If menu.lst does not exist, this is a finding.
