The above rule includes one match key (<em>KERNEL</em>) and one assignment key (<em>NAME</em>). The semantics of these keys and their properties will be detailed later. It is important to note that the match key is related to its value through the equality operator (==), whereas the assignment key is related to its value through the assignment operator (=).
