Is it possible to provide a tool (a shell script?) that would print out
the new would-be name of the interface provided by the user so that it
would be possible to migrate remote systems only accessible via SSH?
I mean, a sysadmin would then be able to determine the new name of the
network interface, reflect this change in the firewall setup and other
relevant places, delete 70-persistent-net.rules and reboot the box
(or may be perform some more involved encantation with calling ifdown /
ip link name ... / ifup while in a screen/tmux session).
