Is it as simple as that? Here is my service file:

[Unit]
Description=SSRemote Server
Wants=network.target
After=syslog.target network-online.target

[Service]
Type=simple
ExecStart=/agi/ssremote/bin/SSRemoteServerLx
Restart=always  #<== This
RestartSec=10   #<== And this
KillMode=process
User=pi

[Install]
WantedBy=multi-user.target

Do these 2 marked lines mean that if the service application just exits (with no
exit code) systemd will restart it after 10 seconds?

And:
Right now I am running it as user pi as shown above, is there some reason I
should run it as root instead?
(I wanted the files created while running to be owned by pi).
