tell users about tor-arm on the tor-relay-debian page
We should tell people about arm on https://www.torproject.org/docs/tor-relay-debian.html.en
What's the right way to run arm with the deb?
sssheep on irc suggested "sudo -u debian-tor arm". Is that indeed the recommended best practice? Or should we recommend that users add themselves to the debian-tor group, and run arm as themselves? Does arm know how to talk to the control socket in the Tor deb? Does the tor-arm package auto build arm knowing where to look?
