I got desperate enough to try ktrace -i on sshd, which reveals that it
is stat()ing /usr/X11R6/bin/xauth.  When I symlink that to
/usr/bin/true, sshd shuts up and runs my rc script.  (I then have other
problems; I get "rejected because of wrong authentication" gubbish
which I have not yet tracked down the cause of.  But the problem I
wrote here about is papered over, though not fixed.  Worth a PR maybe?
Or would this just be punted to the OpenSSH people and ignored?)

Doesn't help (as expected - that's a client-side config, and it's the
server side that's misbehaving here - and yes, I got rid of the symlink
when testing this).
