resolv.conf裡重開都會清除~

請問一下,我已在ifcfg-eth0或ifcfg-eth1裡都有加入dns1=168.95.1.1,但每次重開resolv.conf都不會載入,都會顯示如下:
# Generated by NetworkManager
search com.tw


# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com

我都要在開機完後重新service network reload
resolv.conf才會載入dns ip,不知是那裡有要去改的~
