All right!

Ah, so it exists as a funny prank!  That's good.

(Or maybe it isn't.)

This obvious trap bugs me, but I'm not sure what to do about it. 
That's why I asked how you found it.

- I do like the fact that /gnu/store/xxx is a little microcosm of 
  what the package thinks its world should look like—including 
  /etc.

- Patching hundreds of packages to ‘make 
  sysconfdir=$out/share/doc/examples install’ or so is no 
  improvement.

- /run/current-system/profile/etc *is* the actual system 
  configuration for at least one thing (etc/ssl) so we can't 
  simply delete the former to enforce /etc usage and reduce user 
  confusion.

But this is a tangent.  Happy debuggings,
