Quite the contrary - systemd expects ExecStart command to remain, going into background would be interpreted as "service terminated". To quote systemd: "the service manager will consider the unit started immediately after the main service process has been forked off. It is expected that the process configured with ExecStart= is the main process of the service". > systemd starts processes but it doesn't daemonize them -- the script is > responsible for doing that itself.
