I don't agree so much. some time when a system is reboot unnormally, named doesn't have the chance to remove its pid file. (when OS is shutdown normally, OS sends SIGTERM to named, named can exit and remove its own pid file.) after system is started, the pid number in name's pid file is maybe another process's. so kill -0 `cat named.pid` is successful, but named is not running at this time. Am I right?
