Could you add.
To /etc/tor/torrc please? Then restart Tor?
AppArmor complains about missing mknod © access to /run/tor/log. And I failed to find out how to add an exception to /etc/apparmor.d/local/system_tor. Maybe you can help out?
We can keep /var/log/tor/log to have a log that survives reboot. An additional (multiple instances of the “Log” command seem to be supported by Tor) /var/run/tor/log that only contains messages since last boot would be helpful as well. whonxicheck could grep it for clock related messages and warn if it found something.
