Great post. I am just in the process of building my first CentOS 7 host 
and was wondering whether to use NetworkManager. You've swayed me. I've 
always disabled it on CentOS 6. Your point about these new funky device 
names is really good. I will miss my simple eth0 and eth1 but tech moves on.

Definitely a learning curve with nmcli. Right now I'm at the "Argh! 
WTF!" phase but I'm sure I'll get over it. I got over it with selinux 
once I made the decision to *not* to disable selinux on all my new 
CentOS 6 hosts.

You should move your post onto the wiki.
