 Description:
 
+	REMOVAL UPDATE: The SELinux runtime disable functionality was removed
+	in March 2023, the original deprecation notice is shown below.
+
 	The selinuxfs "disable" node allows SELinux to be disabled at runtime
 	prior to a policy being loaded into the kernel.  If disabled via this
 	mechanism, SELinux will remain disabled until the system is rebooted.
