[systemd-devel] systemd-networkd and interface names

[Matt Zagrabelny]

Greetings,

I am using systemd-networkd and I am wondering how/why the interface names
get chosen.

Scenario:

I am expecting an interface name to be enp1s0. Instead I get eth1.

It appears that eth1 is being referenced in things like:
/etc/default/isc-dhcp-server
/etc/default/minissdpd

If I change those instances of eth1 to enp1s0, then the interface rename
happens as expected:

# dmesg | grep eth1
[    1.751611] tg3 0000:01:00.0 eth1: Tigon3 [partno(BCM95722A2202G) rev
a200] (PCI Express) MAC address 00:10:18:59:c3:6f
[    1.751613] tg3 0000:01:00.0 eth1: attached PHY is 5722/5756
(10/100/1000Base-T Ethernet) (WireSpeed[1], EEE[0])
[    1.751614] tg3 0000:01:00.0 eth1: RXcsums[1] LinkChgREG[0] MIirq[0]
ASF[0] TSOcap[1]
[    1.751616] tg3 0000:01:00.0 eth1: dma_rwctrl[76180000] dma_mask[64-bit]
[   17.763317] tg3 0000:01:00.0 enp1s0: renamed from eth1

Is this expected behavior with the kernel, udev, etc.?

Thanks for any help!
