Hi,
ifrename, iproute2 and udev has capability to rename interface labels.
Years ago I tried to keep interface label consistent with map token in
/etc/network/interfaces on a Debian system. There was an example script
in Debian for it. It worked.
ip command from iproute2 seems to do the trick on a LEAF Bering-uClibc
3.0 Rev 7 uClibc 0.9.28 system as can be seen from following.
nailhead# ip link
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop
link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:10:b5:9a:12:66 brd ff:ff:ff:ff:ff:ff
4: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
link/ether 00:10:b5:9a:0a:bb brd ff:ff:ff:ff:ff:ff
nailhead# ip link set eth1 name eth3
nailhead# ip link
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop
link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:10:b5:9a:12:66 brd ff:ff:ff:ff:ff:ff
4: eth3: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000
link/ether 00:10:b5:9a:0a:bb brd ff:ff:ff:ff:ff:ff
