Overview

FIXME: this whole setup/regular execution is ugly. need to think of a better scheme Motivation behind the ‘setup’ thing:

  • on some platforms we need to do stuff before any of the real recipes are running an example is Darwin where you need to change the default package provider to ‘ports’ BEFORE you define any package resources

  • so we create 2 manifests. one that executes the ‘setup’ recipes, and another one that executes the rest.

#execute(force = false) ⇒ Object
