Set the owner and group of your boot loaders config file to the root user. These instructions default to GRUB stored at /boot/grub/grub.cfg.
Setting the owner and group to root prevents non-root users from changing the file.
Perform the following to determine if the /boot/grub/grub.cfg file has the correct ownership:
stat -c "%u %g" /boot/grub/grub.cfg | egrep "^0 0"
The command should return 0 0 indicating root:root ownership. If the above command emits no output then the system is not configured as recommended.
Run the following to change ownership of /boot/grub/grub.cfg:
chown root:root /boot/grub/grub.cfg
By default, /boot/grub/grub.cfg is owned by root:root.
