How exactly do you rename your interfaces? Do you use a udev rule? Can
you post those scripts/rules?
I had already posted this in PS of my first email. It is two step process.
Here it is again:
Little about tmpeth* naming.
Some old scripts that we have expect interface names starting with eth.
But those names are not predictable.
So to get predictable names starting with eth*, first I temporarily
rename all interface with tmpeth*. This is done via udev rules.
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="XX:XX:XX:XX:XX:XX",
NAME="tmpeth0"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="XX:XX:XX:XX:XX:YY",
NAME="tmpeth1"
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="XX:XX:XX:XX:XX:ZZ",
NAME="tmpeth2"
Then I have a small service (script) which runs before
network-pre.target to convert these names back to eth*
#search for network interface with name starting from "tmpeth" and
rename them to "eth"
/usr/bin/find /sys/class/net -maxdepth 1 -name "tmpeth[0-9]" -type l
-printf "%f\n" | while read tmpiface; do /usr/bin/ip link set dev
"$tmpiface" name "$(echo $tmpiface | sed s/tmpeth/eth/)"; done
This ensures that I have predictable names starting with eth*. And it is
working fine from 2-3 years. Even with current issue, name assignment is
working fine.
