Okay, diving in where angels don't know what the hell they are doing. (I 
would love for James to pipe in here.) *But*, it seems like in the 
section in his posting on setting up a fixed IP address (which is my 
immediate interest):

nmcli conection modify  connection.autoconnect yes ipv4.method manual ipv4.addr "" ipv4.dns "," ipv4.gateway

Does not reference an actual interface name and nmcli is figuring 
everything out for you. *Unless* he is using "connection" here as a 
euphemism for an interface.

If "connection" is the actual string then a script would work regardless 
of host.
