Daemonize no belongs on the command line, nice job!

--daemonize no will hang the redis

@willzhang
Mode --supervised systemd requires --daemonize no. Otherwise, it should be turned on.

The ExecStop value is problematic if there is auth set. It seems to work fine without it because systemd will just send a SIGTERM to the process.

@crussell52 is there a better way to handle ExecStop to account for both auth and non-auth cases?

Without defining an ExecStop, systemd will send a SIGTERM to the process. At least in Redis 6, the server process seems to recognize that as a shutdown signal.

@crussell52
The reason to include ExecStop was to distinguish Redis instances running on different ports.
But looks like you're right, omitting the stop command will work in this case as well.
