I do not remember for certain if I did that earlier.

Anyway, I've tried everything again now: removed udev rules, placed network units, updated initramfs, rebooted. It works now, system no longer tries to rename the first interface it comes across into the first configured name it comes across.

Either unupdated initramfs caused this, or something was fixed during the last year.

How could the lack of rules in initramfs trigger spontaneous rename ignoring match filters anyway?
