Thanks once again for the clarification! I suppose I should ask the more general question of whether the different L4Re mechanisms are documented in a manual or something of that nature. Although the reference documentation covers some of the concepts, along with APIs for use by applications, but not necessarily various framework-level abstractions (like Remote_app_model), it would be informative to be able to read something that discusses the techniques involved in building a system on top of Fiasco. At the moment, I am just trying to persuade a program to run in a new task, which will hopefully only be a matter of properly initialising the details of the program environment. As well as paging in the appropriate segments of the binary in the right places, of course.
