Jessie to Stretch Upgrade: Enable Predictable Network Interface Names

[debian-lists@patschie.de]

Hi,

I’m running into some troubles to enable the predictable network interface names for a system upgraded from Jessie.

What I figured out so far:
Setting net.ifnames=1 on the kernel command line doesn’t help and seems no longer to be supported parameter (at least "sysctl - a" doesn’t show it).
Removing any /etc/udev/rules.d/ file handling the network interface doesn’t bring the desired effect of having predictable network interface names.

I started now to compare /lib/udev/rules.d from a clean stretch installation with the files on a upgraded system, the clean installation has much more files.
So next try reinstalling udev to get all missing/new rule files from stretch, but that didn’t work either.

Any ideas what I could try next or missed to check?

Thanks a lot.
