Automation is all very well once the network link is up and working so you can reach the automation
But the reality is you put someone who knows what they're doing in front of a machine where the network connection isn't working, the first things they're going to be doing is ifconfig and ping 8.8.8.8 - which they'll be doing from memory, because you can't google anything when your network connection isn't working.
The fact that IPv6 will deprecate both ifconfig and 8.8.8.8 to me seems emblematic of why the adoption has been going so badly.
