 in config/strings.cfg:
 {{{
 msg.setup.arm_is_running_as_root Arm is currently running with root
 permissions. This isn't a good idea, nor should it be necessary. Try
 starting arm with "sudo -u {tor_user} arm" instead.
 }}}

 Telling the user to run arm as the tor user exposes all of /var/lib/tor/
 to arm, which is probably more than needed and likely more than expected.

 At least on debian, the right answer is "sudo adduser $USER debian-tor"
 and then run arm as the normal user (after logout/login as needed). See
 #10700 for where this topic came up.
