I have a freshly installed Debian Jessie. I had two NICs, which were eth0 and eth1, now I took out one, however I still have eth1 left in the system:
% dmesg ... tg3 0000:03:00.0 eth0: Tigon3 [partno(BCM95754) rev b002] (PCI Express) MAC address 00:1a:a0:ac:f6:2d tg3 0000:03:00.0 eth0: attached PHY is 5787 (10/100/1000Base-T Ethernet) (WireSpeed, EEE) ... systemd-udevd: renamed network interface eth0 to eth1
Is there a way to ask not to rename the interface and just keep eth0? Thanks.
