(In reply to Jonathon Anderson from comment #12)
> Correct me if I'm wrong, but isn't the solib mapped before DT_AUDIT is re=
ad?

See elf/rtld.c:dl_main.
At around line 1844 you see
  /* If we have auditing DSOs to load, do it now.  */
Then LD_PRELOADs are loaded, then DT_NEEDED.
Then you have la_activity and la_objopen.
So I think auditor is loaded first and that's
intentional.

Well, both parts are not true. :)
It will be applied to the lib being loaded,
AND I want to customize another lib loaded
even later rather than this one.
