This still suffers from sshd using its compiled-in defaults for things
like host key file location, etc., so it complains if those aren't
available, but the grep ignores those, anyway. This way at least
guarantees that the configuration file used by sshd is completely under
curl's control, so it's definitely better. The other option would be to
write out an curl_sshd_config for each iteration, but that probably won't
actually improve anything given current versions of sshd.
