Comment (by dgoulet):

 From IRC, we'll got with `3)`. I'll propose a patch soon hopefully.

 {{{
 < nickm> dgoulet: if you had to pick tomorrow, which option would you pick
 (for #14917)
 < dgoulet> nickm: "Error at startup. Tor doesn't start and we tell
 operator why.", it's either that or we allow exiting at our Guard which
 I'm unsure of the implication of that
 < nickm> what about "Error at startup. Tor doesn't start and we tell the
 operator why, and how to fix it"
 < dgoulet> nickm: ah well of course, error means lots of info to help op
 :)
 < dgoulet> nickm: with man page update also
 < nickm> dgoulet: okay.  I think that 1-3 are mostly the same code.
 < nickm> dgoulet: and if you think 3 is best, 3 is probably better than
 nothing
 < nickm> so the only question is, is 3 better than 4?
 < nickm> I think it is.
 < nickm> so let's go with your idea there.
 < nickm> copy our discussion, minus other people's text, into the ticket,
 and code as seems best?
