tor-server loses all state after reboot
The tor-server stores its state in /var/run/tor/.tor. Since /var/run is a soft-link to /run and that is mounted as tmpfs, the data, like the server-descriptor, is lost after a reboot. I run a high-traffic tor-node on alpine and this is very annoying.
Since this is a community package, this may be the wrong place to file a bug. If there is a better place, please let me know.
