Package: src:linux Version: 4.19.37-5+deb10u2 Severity: normal Hi, installing the latest update caused our NICs to be renamed from "enoX" back to "ethX". We first experienced this issue on Debian/buster on HPe DL360g10 and now found the same issue with the latest upload of the same kernel to stretch-backports.
We're now working around this issue by using $ cat /etc/systemd/network/101-onboard-rd.link [Link] NamePolicy=onboard kernel database slot path MACAddressPolicy=none That said on a system still running Debian/stretch with the old working kernel, without the systemd workaround applied I've the following: svenhoexter@docker-018:~$ uname -a Linux docker-018 4.19.0-0.bpo.5-amd64 #1 SMP Debian 4.19.37-4~bpo9+1 (2019-06-19) x86_64 GNU/Linux svenhoexter@docker-018:~$ udevadm test-builtin net_id /sys/class/net/eno5 2>/dev/null ID_NET_NAME_ONBOARD=eno5 ID_NET_NAME_PATH=enp93s0f0 svenhoexter@docker-018:~$ SYSTEMD_LOG_LEVEL=debug udevadm test-builtin net_setup_link /sys/class/net/eno5 calling: test-builtin === trie on-disk === tool version: 232 file size: 8441068 bytes header size 80 bytes strings 1846908 bytes nodes 6594080 bytes Load module index Found container virtualization none timestamp of '/etc/systemd/network' changed Skipping overridden file: /lib/systemd/network/99-default.link.
