Seems NetworkManager is driving everyone bonkers still and not just me. I did a GUI install and disabled the use of NetworkManager yet the stupid thing still seems to blow away my resolv.conf and better still not populated it even though I have things defined in ifcfg-eth0.
See here. I’ve experienced these exact same issues as the folks posting on the thread. I remember having this issue back on CentOS 6.0, guess it’s still not fixed.
