Names of network devices

Hello,

On an NFS server, I am maintaining several chroot environments, with
several different versions of Debian and Ubuntu. Clients can use these
chroot environments as NFSROOTs. After installing the chroot for Ubuntu
16.04 and booting a client, for the first time the name of the network
interface was not eth0 any more, but something with en at the beginning, I
do not remember the exact name. Well, this new scheme to name network
interfaces had been reported about.

But yesterday, I upgraded the the kernel of the Ubuntu 16.04 chroot,
current version is 4.4.0-47-generic, and suddenly, when I boot the client,
the network interface's name is eth0 again.

Did anyone else discover that, after an Upgrade to Kernel
4.4.0-47-generic, network interfaces are named following the old scheme
again? Or is there a problem in my chroot - what I believe is unprobable,
because I am sure that I did make another change that could affect
interface names?

And if it is the kernel - does anybody know if future xenial kernels will
keep the eth scheme or return to en scheme?

Regards
  Christoph

Viele Grüße
  Christoph
