Run the following command to remove the selinux=0 and enforcing=0 parameters: # grubby --update-kernel ALL --remove-args "selinux=0 enforcing=0" Run the following command to remove the selinux=0 and enforcing=0 parameters if they were created by the deprecated grub2-mkconfig command: # grep -Prsq -- '^\h*([^#\n\r]+\h+)?kernelopts=([^#\n\r]+\h+)?(selinux|enforcing)=0\b' /boot/grub2 /boot/efi && grub2-mkconfig -o "$(grep -Prl -- '\h*([^#\n\r]+\h+)?kernelopts=([^#\n\r]+\h+)?(selinux|enforcing)=0\b' /boot/grub2 /boot/efi)"
