Apparently not. From https://lists.debian.org/debian-user/2015/08/msg01083.html * The mechanism for providing stable network interface names changed. Previously they were kept in /etc/udev/rules.d/70-persistent-net.rules which mapped device MAC addresses to the (arbitrary) name they got when they first appeared (i. e. mostly at the time of installation). As this had several problems and is not supported any more, this is deprecated in favor of the "net.ifnames" mechanism. And in https://lists.debian.org/debian-devel/2015/06/msg00018.html some 4 weeks ago I sent a first proposal to change persistent network interface naming away from our current /lib/udev/rules.d/75-persistent-net-generator.rules (which is inherently racy and doesn't apply to all virtualized environments) to udev's "net.ifnames": -- Brian.
