  @install_steps ||= {}
  @install_steps[id] = block
end

#on_prepare(id = nil, &block) ⇒ Object

Run block on prepare step. id identifies the block uniqueness in the steps. registering a block with same id multiple times replaces old block by new one. if id is nil the block location in source code is used as an id
