The trick is we don't pass the logfile fd to the job (the jobs stdout+stderr are connected to one
end of a pty). Regarding rotation, Upstart detects if the logfile that it manages was deleted. If
so, it simply closes and reopens the corresponding file. This allows tools like logrotate to
handle rotation.
Kind regards,
James.
