create_world_atom(pkg, args_set, root_config, before_install=False)¶
Create a new atom for the world file if one does not exist. If the argument atom is precise enough to identify a specific slot then a slot atom will be returned. Atoms that are in the system set may also be stored in world since a user might want to select multiple slots of a slotted package like gcc for example. Unslotted system packages will not be stored in world.
