What I would rather do is make the daemon aware of what can be
scheduled, when.

I.e. each backend would have a function:

get_no_queue_objects:
return PK_ROLE_ENUM_SEARCH_GROUP | PK_ROLE_ENUM_SEARCH_GROUP

get_force_all_queue_objects
return PK_ROLE_ENUM_REFRESH_CACHE

So the daemon knows what to do. Have a look in
pk_transaction_list_commit in src/pk-transaction-list.c for inspiration.

Ideas?

Richard.
