The consensus of the list seemed to be that I should change the PEERDNS variable. It seems not to be working. The machine rebooted yesterday, /etc/resolv.conf got rewritten again. And yet: find /etc/sysconfig/ -type f -exec grep -iH 'peerdns=' {} \; /etc/sysconfig/network-scripts/ifcfg-eth0:PEERD

My machine has a static IP, with dhcp and IPv6 disabled. Every time I reboot, some process rewrites /etc/resolv.conf, including a comment about dhcpclient. The only package I have installed that shows up in "rpm -qa|grep -i dhcp" is dhcpv6-client-1.0.10-16.el5, and nothing in there is named dhcpcli
