Creating a Capistrano task that performs different tasks based on role

I'm looking for a way to call a single Capistrano task to perform different things to different roles. Is Capistrano able to do this, or do I have write a specific task for each role?

From stackoverflow

• The standard way to do this in Capistrano:

  task :whatever, :roles => [:x, :y, :z] do
    x_tasks
    y_tasks
    z_tasks
  end
  
  task :x_tasks, :roles => :x do
    #...
  end
  
  task :y_tasks, :roles => :y do
    #...
  end
  
  task :z_tasks, :roles => :z do
    #...
  end
  

  So yes, you do need to write separate tasks, but you can call them from a parent task and they will filter appropriately.
