This was how it used to work long ago (I forget exactly how long). I had things set up so that GDB's standard ELF shared library code would find KLDs automatically - you can see remnants of this in link_elf.c in 'ifdef GDB' sections which build an RTLD-like list of loaded files which GDB looked for starting at the global symbol r_debug. --Apple-Mail-25-40927724--
