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!
