 CookieAuthentication is not set, and I have to write torrc again.

 This sounds like something that's the package manger/user's problem.  In
 general I would be against adding something like this, unless it was
 runtime configurable and defaulted to off, defeating the purpose of adding
 this feature in the first place.

 IMO it is not tor's business to dictate policy, and having a magical unix
 socket only for the superuser (which isn't the user tor is running as on a
 sane system), is dictating policy (a magical unix socket for the tor user
 is equivalent to enabling CookieAuthentication).

 FWIW: https://gitweb.torproject.org/debian/tor.git/tree/debian/tor-
 service-defaults-torrc

 Fair enough.

 What do you envision happening if a user happens to run more than 1 tor
 instance on a given box, and how will you disambiguate the various
 directories under `/tmp`?
