Comment (by teor):

 Replying to [comment:68 nickm]:

 correctly for servers without DirPort support.

 We can do this in chutney by commenting out the line:
 {{{
 DirPort $dirport
 }}}
 in chutney/torrc_templates/relay-non-exit.tmpl

 It's important that these relays work in mixed dirport / no dirport
 networks, which probably means creating a new torrc template and a new
 network, then testing that network as part of make test-network-all in
 tor.

 The torrc_templates include structure is currently:
 * common.i
   * relay-non-exit.tmpl
     * relay.tmpl (also includes exit-v4.i and exit-v6.i)
     * relay-exit-v4-only.tmpl (also includes exit-v4.i)
     * relay-exit-v6-only.tmpl (also includes exit-v6.i)

 It could be changed to:
 * common.i
   * relay-non-dirport.tmpl (contains the previous content of relay-non-
 exit.tmpl without DirPort)
     * relay-non-exit.tmpl (also includes dirport.i, which contains
 `DirPort $dirport`)
       * relay.tmpl (also includes exit-v4.i and exit-v6.i)
       * relay-exit-v4-only.tmpl (also includes exit-v4.i)
       * relay-exit-v6-only.tmpl (also includes exit-v6.i)

 But then we would also need to make templates for exit relays without a
 dirport:
 * common.i
   * relay-non-dirport.tmpl (contains the previous content of relay-non-
 exit.tmpl without DirPort)
     * relay-non-dirport-exit-v4-v6.tmpl (also includes exit-v4.i and
 exit-v6.i)
     * relay-non-dirport-exit-v4-only.tmpl (also includes exit-v4.i)
     * relay-non-dirport-exit-v6-only.tmpl (also includes exit-v6.i)

 (We need to do a better job of turning features like this on and off in
 chutney 2.0.)
