I was a bit surprised to find that the chapter on deploying apps has been more or less replaced with instructions on installing Passenger.
While I agree that Passenger is the way forward the chapter stops once you’ve got Passenger serving your app from the home directory it was developed in. No capistrano. No per-release uploads. Just setup Passenger to serve up your development code.
I realise that ‘Deploying Rails Apps’ is essentially redundant six months after going to press because it does not mention Passenger at all but cutting Capistrano out of the pickaxe book completely seems a bit cynical.
