systemd (241-4) unstable; urgency=medium DRM render nodes (/dev/dri/renderD*) are now owned by group "render" (previously group "video"). Dynamic ACLs via the "uaccess" udev tag are still applied, so in the common case things should just continue to work. If you rely on static permissions to access those devices, you need to update group memberships accordingly to use group "render" now. -- Michael Biebl Fri, 17 May 2019 19:15:32 +0200 systemd (220-7) unstable; urgency=medium The mechanism for providing stable network interface names changed. Previously they were kept in /etc/udev/rules.d/70-persistent-net.rules which mapped device MAC addresses to the (arbitrary) name they got when they first appeared (i. e. mostly at the time of installation). As this had several problems and is not supported any more, this is deprecated in favor of the "net.ifnames" mechanism. With this most of your network interfaces will get location-based names. If you have ifupdown, firewall, or other configuration that relies on the old names, you need to update these by Debian 10/Ubuntu 18.04 LTS, and then remove /etc/udev/rules.d/70-persistent-net.rules. Please see /usr/share/doc/udev/README.Debian.gz for details about this. -- Martin Pitt Mon, 15 Jun 2015 15:30:29 +0200
