Xenial/4.4 kernel does not honor biosdevname=0

[Jeffrey Walton]

I installed the Xenial daily testing image dated 2-13-2016 (ttp://cdimage.ubuntu.com/lubuntu/daily-live/20160213/xenial-desktop-i386.iso).

I'm booting the kernel with the following:

    ipv6.disable=1 biosdevname=0 longhaul.enable=0 audit=0 quiet splash

However, eth0 is being named enp3s0:

    $ dmesg | egrep 'r8169|net|eth'
    [ 0.017363] Initializing cgroup subsys net_cls
    [ 0.017377] Initializing cgroup subsys net_prio
    [ 3.150713] r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
    [ 3.150735] r8169 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control

    [ 3.263623] r8169 0000:03:00.0 enp3s0: renamed from eth0

    [ 17.381617] r8169 0000:03:00.0 enp3s0: link up

And:

    $ cat /etc/network/interfaces
    # interfaces(5) file used by ifup(8) and ifdown(8)
    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet dhcp

And:

    $ ls -Al /etc/udev/rules.d/
    total 0

The thing that looks most different (to me) is systemd.

The desired behaviour can be achieved by adding the following to the default boot options:

biosdevname=0 net.ifnames=0

Any solution to this? - I'm passing net.ifnames=0 biosdevname=0 but after the latest apt-get upgrade, it is ignored :( --

net.ifnames=0 biosdevname=0 works for me on xenial/amd64 4.4.0-36-generic
