Comment (by arma):

 Ok, I added
 {{{
 @@ -683,6 +683,8 @@ dirserv_add_descriptor(routerinfo_t *ri, const char
 **msg, c
 onst char *source)
      goto fail;
    }

 +  log_info(LD_DIR, "Assessing new descriptor: %s", ri->platform);
 +
    /* Check whether this descriptor is semantically identical to the last
 one
     * from this server.  (We do this here and not in
 router_add_to_routerlist
     * because we want to be able to accept the newest router descriptor
 that
 }}}

 and am now running
 {{{
 tail -f moria1-info|grep -A1 "not specified"|grep Assessing
 }}}
 So far it's just getting bombed by two relays:
 Me0W:
 https://metrics.torproject.org/rs.html#details/91954A36BB0C32861325D99CCC264E619C75C437
 running 0.2.5.16
 and happachwg:
 https://metrics.torproject.org/rs.html#details/64342130F715C4CD0DFF7C207D996600F41CE7C1
 running 0.2.5.14
 but I'll leave it for some days and see if we get more variety.
