Comment (by asn):

 BTW, there is now this code in `options_validate()`:
 {{{
     /* same for guardfraction file */
     if (options->GuardfractionFile && !old_options) {
       file_status_t fs = file_status(options->GuardfractionFile);
       if (fs == FN_EMPTY) {
         REJECT("GuardfractionFile set but it's an empty file? Failing");
       } else if (fs != FN_FILE) {
         REJECT("GuardfractionFile set but not a file? Failing");
       }

       dirserv_read_guardfraction_file(options->GuardfractionFile, NULL);
     }
   }
 }}}

 Nick, do you think we should be less strict and not `REJECT` if we can't
 find the file?
 We could just issue a warning and proceed with our business, without
 considering guard fraction at all.

 This seems to be the behavior of the `V3BandwidthsFile` option, and it
 might be better because Tor won't refuse to start if the guardfraction
 script is misbehaving and doesn't output a file.
