I have use --user teddy --group teddy in the upstart config, and even though I execute "start prg" and "stop prg" from the root account, all the starman processes are owned by teddy account. And there are 11 processes, even though I asked starman to run 10 children, so the master process is also owned by teddy account. >>> To be honest, I kind of hate upstart.

For example, I can manage apache2 process using service apache2 status but not status apache because apache2 uses a SystemV script. I read somewhere that upstart can work somehow with upstart scripts, but that the old SysV init scripts are also executed... but I don't know if it can also work in the same way with SysD scripts...
