Description of problem:

The control loop that manages /var/run/keepalived/iptables-rule-exists looks at the error returned by os.Stat and decides that the file exists as long as os.IsNotExist returns false. In other words, if the error is some non-nil error other than NotExist, the sentinel file would not be created.
