[CentOS] CentOS 7 : network interface renamed from eth0 to eth1 after reboot

There may be ways to force NIC naming, I've done so but only on Ubuntu so you'll need to do the research if it's important to you.  Things to look for based on my experience: 70-persistent-net.rules, net.ifnames=0, biosdevname=0.

Thanks for the heads up.

I experimented quite a bit, and found some surprising behavior. So I documented
everything in a little blog article.
