Package: release-notes Severity: minor X-Debbugs-Cc: aip...@outlook.com I updated a staging bookworm VM with VirtIO NIC to trixie and temporarily lost network access because enp6s18 became ens18, and subsequently /etc/network/interfaces 'allow-hotplug enp6s18' no longer functioned. (Weirdly, 'auto' still works.)
systemd v257 release notes and man subpage net-naming-scheme show new "PCI slot number is now read from firmware_node/sun sysfs file" and documented 'net.naming_scheme=v255' kernel cmdline reverted the changes back to what it was in bookworm with systemd v252. The Debian NetworkInterfaceNames wiki page was helpful to debug this. The listed udevadm command shows that naming scheme v257 has new ID_NET_NAME_SLOT=ens18 entry. I guess by the usual schedule there are several months to go until trixie becomes the stable release, and the above could change again. That said I might suggest a short release notes entry in Debian. systemd's own comment on this seemed easy to miss.
