bundle) to be set through the environment variable
  ‘OPENSSL_X509_CERT_FILE’.  This is necessary because the default
  location ($out/ssl/cert.pem) doesn't exist, and hardcoding something
  like /etc/ssl/cert.pem is impure and cannot be overriden
  per-process.  For security, the environment variable is ignored for
  setuid binaries.
