+Subject: [PATCH hurd 09/14] boot: improve the demuxer
+
+Handle multiple request types as recommended by the Mach Server
+Writer's Guide section 4, subsection "Handling Multiple Request
+Types".  This avoids initializing the reply message in every X_server
+function.
+
+* boot/boot.c (mig_reply_setup): Provide local version.
+(request_server): Rename to `boot_demuxer', and improve the dispatch.

+Subject: [PATCH hurd 13/14] hurd: add `proc_make_task_namespace'
+
+Add a new RPC to the process protocol to create task namespaces.
+These can be used by an unprivileged process to claims the
+responsibility to manage all tasks in this namespace.  Any task
+created in this namespace will automatically be declared a child of
+the root process, and a `mach_notify_new_task' message is sent to a
+given port.  If the root process dies, the proc server will terminate
+all tasks in the namespace.
+
+* hurd/process.defs (proc_make_task_namespace): New RPC.
