After replacing the second network card with a new one, NetworkManager

1. Where does NetworkManager hold its definitions of network
   interfaces?
Edit:
/etc/udev/rules.d/70-persistent-net.rules

Delete line ending with NAME="eth1"
Rename line ending with NAME="eth2" to NAME="eth1"
Reboot.

Thank you very much.  My own problem is solved, but my understanding
is incomplete.

Now I need to find the documentation for this and read it.  There is
not a huge amount of detail here:
file:///usr/share/doc/udev-145/writing_udev_rules/index.html#example-netif

Why does this override the /etc/sysconfig/network-scripts/ifcfg-eth*?
And since it does, the jurisdiction of the ifcfg-eth* scripts seems
encroached.

It seems confusing to me.

I need to understand how this gets written.  I suppose I need to read
the startup scripts and try to understand the division of labour
between NetworkManager, udev and /etc/sysconfig/network-scripts/*.

I wish there was documentation that shows how these all coexist and
cohere together.  Does such documentation exist?
