When running sudo systemctl status redis, I see this error message:

systemd[1]: redis-server.service: Can't open PID file /run/redis/redis-server.pid (yet?) after start: Operation not permitted

However, Redis seems to work fine. I can run redis-cli, do the traditional ping test, create a database, etc. The /var/run/redis folder is owned by redis, so is the redis-server.service. I did set supervised to systemd in redis.conf since I'm on Ubuntu and systemctl tells me the server is running and active.

Should I worry/anticipate an issue or is it nothing?
