Check Text ( C-21837r490411_chk )

This check applies to the global zone only. Determine the type of zone that you are currently securing. # zonename If the command output is "global", this check applies. On systems that have a ZFS root, the active menu.lst file is typically located at /pool-name/boot/grub/menu.lst where "pool-name" is the mount point for the top-level dataset. 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 Check the ownership of the menu.lst file. Procedure: # ls -lL /pool-name/boot/grub/menu.lst or # ls -lL /boot/grub/menu.lst If the owner of the file is not root, this is a finding.

Fix Text (F-21836r490412_fix)
Change the ownership of the file. # chown root /pool-name/boot/grub/menu.lst or # chown root /boot/grub/menu.lst
