What parts of my tor relay configuration/operation does this ansible role cover?

tldr: everything is taken care of ;)

Tor (Repo and) Package Installation

• Linux
  • APT: enables torproject.org's repository and installs the repo signing key
  • RPM: enables EPEL on CentOS
  • CentOS/Fedora: takes care of SELinux configuration (enable 'tor_can_network_relay' boolean)
• OpenBSD:
  • package installation via pkg_add (expects you to have the snapshot repository enabled in /etc/pkg.conf - until OpenBSD 5.9 is released)
  • takes care of sysctl/kern.maxfiles and login.conf/openfiles-max
• FreeBSD:
  • installs the tor package (via pkg)
  • take care of kern.ipc.somaxconn + kern.ipc.nmbclusters

Tor Instance Creation

• (offline+online) key generation (on the ansible host)
• transfers RSA and online Ed25519 keys to the relay
• creates multiple tor instances on a single server (default: 2 per available IP address, configurable)
• takes care of DataDirectory creation and filesystem permissions
• runs every tor instance with a distinct system user
• startup configuration: enable all tor instances to start at boot
  • Linux: systemd multi-instance service file ([email protected])
  • OpenBSD: rcctl - linking the default rc script once per tor instance
  • FreeBSD: /etc/rc.local
• Tor Instance Configuration (torrc)
  • automatic MyFamily configuration
  • ContactInfo configurable
