+    <sekon_> is __dir_lookup a RPC ??
+    <sekon_> where can i find the source of __dir_lookup ??
+    <sekon_> grepping most gives out rvalue assignments 
+    <sekon_> -assignments 
+    <sekon_> but in hurs/fs.h it is used as a function ??
+    <pinotree> it should be the mig-generated function for that rpc
+    <sekon_> how do i know how its implemented ??
+    <sekon_> is there any way to delve deeprer into mig-generated functions 
+    <tschwinge> sekon_: The MIG-generated stuff will either be found in the
+      package's build directory (if it's building it for themselves), or in the
+      glibc build directory (libhurduser, libmachuser; which are all the
+      available user RPC stubs).
+    <tschwinge> sekon_: The implementation can be found in the various Hurd
+      servers/libraries.
+    <tschwinge> sekon_: For example, [hurd]/libdiskfs/dir-lookup.c.
+    <tschwinge> sekon_: What MIG does is provide a function call interface for
+      these ``functions'', and the Mach microkernel then dispatches the
+      invocation to the corresponding server, for example a /hurd/ext2fs file
+      system (via libdiskfs).
+    <tschwinge> sekon_: This may help a bit:
