[seL4] propagating initial thread's capabilities

The rootserver gets various caps setup for it by the kernel (see Table 9.1 in the manual). This includes the gobal ASID, IRQ, Domain, and Sched controllers. I need these caps in a process created by the rootserver. This is within a CAmkES environment. So far I've created CAmkES component attributes that signal the rootserver should hand-off a cap by moving the rootserver's cap to the designated CNode just before it terminates. This involves modifications to CAmkES, capDL, and the rootserver. Is there a better way? Is there an existing example of doing this? Are any of these global objects accessible some other way than hand-off from the rootserver? -Sam
