Public bug reported:
$ ip link show
...
2: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP
mode DEFAULT group default qlen 1000
link/ether d0:50:99:76:a1:bf brd ff:ff:ff:ff:ff:ff
$ cat /etc/systemd/network/eth0.link
[Match]
MACAddress=d0:50:99:76:a1:bf
[Link]
Name=eth0
I am pretty sure that MAC addresses do match
And I don't change net.ifnames to 0 :
$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.4.0-87-generic.efi.signed
root=/dev/mapper/vg_smart-root_smart ro
then :
$ sudo udevadm test-builtin net_setup_link /sys/class/net/enp2s0

ID_NET_LINK_FILE=/lib/systemd/network/99-default.link
Unload module index
Unloaded link configuration context.
(and, surely, the interface is renamed from eth0 to enp2s0 on boot, but
not renamed back afterwards)
can you please tell where I could be wrong ?
on my existing systems I still keep MAC->ifname relations in
/etc/udev/rules.d/70-persistent-net.rules inherited from past Ubuntu
versions. But this is a new setup of Ubuntu 16.04 and I would like to
configure it in the new & recommended way.
thanks in advance for your replies
