Why, in the RBAC system, is task_id different from script_id?
Because this arrangement gives me the ability to run the same script with different settings, thus changing its behaviour. If the differences in behaviour between one task and another are very slight, this saves the effort of having to create a complete new script for just a minor difference. For example, in the RBAC system there is a script called mnu_task_list.php which will read records from the MNU_TASK table and display them. However, entries on this table are categorised by task_type and I may want the list automatically restricted to one task_type or another.
