Running a network facing daemon written in C as root is not a good idea. Introduce a redis system user/group for that.
A drawback is that now redis can no longer increase the number of open fds to 10000 (MaxClients). If this is needed the ulimit needs to be tweaked in the init script or systemd unit file. This only affects systemd based systems.
