Version-Release number of selected component (if applicable): dhclient-3.0pl1-9 How reproducible: Always Steps to Reproduce: 1. Make changes to /etc/ntp.conf 2. run dhclient 3. Actual Results: ntp.conf has been overwritten Expected Results: ntp.conf should have remained unchanged. Additional info: Lines 149-156 of /sbin/dhclient-script overwrite /etc/ntp.conf
If you set PEERDNS=no in your /etc/sysconfig/network-scripts/ifcfg-eth0 script using the latest dhclient from rawhide this problem will go away.
Looking in the script, it appears to be PEERNTP=no not PEERDNS=no In a simple test, this seemed to work.
