"docker run" appears to rename my eth0, wreaking ifupdown ...
github.com › moby › mobySep 24, 2015 · This log appears to rename your host eth0, but it actually is renaming the container's eth0 back to vethb817d6a. The kernel logs normally don't show this difference i.e that this is happening in a different namespace other than the host namespace. And after renaming we move the veth interface back to host namespace before bridge driver deletes it.
