go - Golang catch signals

Question

I want to implement a "process wrapper" in Go. Basically what it will do, is launch a process (lets say a node server) and monitor it (catch signals like SIGKILL, SIGTERM ...)

I think the way to do is to launch the node server in a go routine using syscall.Exec:

func launchCmd(path string, args []string) {
  err := syscall.Exec(path, args, os.Environ())
  if err != nil {
    panic(err)
  }
}

Then I'd like to catch every possible signals generated by the command executed by syscall. I'm pretty new to Go, any help would be appreciated.
