Comment:

 I want DNS to work by default in chutney, and I want offline use to work
 even on macOS (and other OSs that have no resolv.conf).

 I think a good way to fix this is to do the thing that will work once
 #21900 is fixed in tor.

 So we should make working DNS the default, and have an --offline option.
 (Or, even better, we could check if the ServerDNSResolvConfFile exists,
 and if it doesn't, we should apply a workaround, which can be switched
 off.)
