Hello Andreas,

Not correct: you still need to use --pidfile. --pidfile does not tell
start-stop-daemon to create the PID file, but it will check whether the
process really created it.
OpenSSH also creates its own PID file, so could you rework to really
follow the S50sshd example?
Thanks a lot!
Thomas
