It's maintenance but this one is "responsive" maintenance. It's not aiming at the status quo. The current Linux is serving the current mix of Linux applications - much broader and different from the "old" one. It's not just keeping it going until better replaces it. It is ITSELF the better thing that constantly replaces it. Which is all the more admirable. And results is well deserved increased market share. It is "building".
