Comment (by arma):

 nusenu: right, the tor-relay-debian page did indeed assume you were using
 the deb.

 atagar, the goal here is to provide some concrete advice for all the
 people who were trained by arm in the past to su to debian-tor and run arm
 as the debian-tor user. That was a bad idea (because it gives arm
 permissions to things that it doesn't need). The better idea is to add
 the-user-that-will-run-nyx to the debian-tor group, and then use the fact
 that the controlsocket is reachable by anybody in the group so
 authentication can happen smoothly.

 To be more specific, I suggest the question would be something like "How
 should I connect nyx to my relay on Debian?" and the answer would be
 something like "as the user that will be running nyx, run "sudo adduser
 $USER debian-tor" to add your user to the debian-tor group so it can reach
 Tor's controlsocket. Then log out and log back in (so your user is
 actually in the group), and run nyx. This approach is safer than the one
 where you run nyx as the debian-tor user directly, since in that case
 you'd be giving nyx more access to your Tor private files than it needs."
