That's odd, as /etc/resolv.conf should only change when your network 
changes. Typically that would be when a new connection is made or one is 
shut down. Do you have anything odd with DHCP on your network? Are there 
any issues with your cables?

Well, if you disble network manager, you will need to enable network or 
you network interfaces won't be set up. So you can't just blindly disable it. 
For now the network service will do what you want.
