How do I LOCK-IN namserver ijn resolv.conf so it cannot be changed by Fedora ?
The (or maybe "an") official way: Change every /etc/sysconfig/network-scripts/ifcfg-* file to have a line that says "PEERDNS=no" (then shutdown and reboot so it will actually see the PEERDNS setting, then modify resolv.conf after the reboot cycle).
The unofficial "big hammer" way:
chattr -i /etc/resolv.conf
That makes the file immutable so even root can't change it.
