Re: [CentOS] From Networkmanager to self managed configuration files

The recommended configuration for EL7 is to use NetworkManager unless you have a very specific edge case preventing you from doing so:

The truth is a lot of us run servers that don't need to have their network "managed" by Networkmanager.

We just need to set an IP address, subnet mask, gateway, and DNS servers and we will never be changing that configuration ever again for the entire life of the server. Any 3-4 line script that does the job is sufficient, servers don't need gimmicks, they're not going to be hotspotting on wireless networks, the cable goes in, the server enters production and that's it!
