 Replying to [comment:5 nickm]:
 > Why do we want to make everybody a directory mirror again?

 We used to only separate the "is a directory mirror" functionality because
 you had to open a separate port, make port forwarding work, etc. Now you
 don't have to. The only reasons not to make everybody a dir mirror are
 that they would fetch, store, and serve more stuff. I don't think the
 overhead is bad.

 To answer barkerjr's question, about half the relays are directory mirrors
 currently. The authorities can handle it.

 Also, when we deploy the directory guard design, we'll want all guards to
 be directory mirrors.

 I'll turn the question around: why not make everybody a dir mirror? It's
 cheap and now that you don't need a separate port for it, there's no extra
 thing the operator needs to do.

 I wouldn't mind that in the meantime.

 > (The v2dir flag was a mistake, but this is not equivalent.  V2Dir meant
 "my version is X"; an IsDir flag would mean "is a directory cache that
 answers begindir")

 "this" in this case is a v3dir flag. I think a v3dir flag would be a
 mistake for the same reason the v2dir flag was a mistake. If somebody
 wants to make this trac ticket be about an IsDir flag, we should change
 the summary line.
