iptables saveが失敗する。 restorecon: command not found

iptables saveを行うと、エラーが出る。

iptables: Saving firewall rules to /etc/sysconfig/iptables: /etc/init.d/iptables: line 274: restorecon: command not found```
 ここによると、iptablesがpolicycoreutils というパッケージに依存しているが上手く入っていないために発生するようだ。 

<a href="http://www.centosblog.com/iptables-restorecon-command-not-found/" target="_blank">http://www.centosblog.com/iptables-restorecon-command-not-found/</a> 対処としては、yumでpolicycoreutilsを入れれば良いらしい。 

yum install policycoreutils
