I noticed the following lines in my journal: r9-008cln systemd-udevd[2305]: Specified group 'render' unknown After grepping the /lib/udev for render, I found: r9-008cln /lib/udev # grep -r render * rules.d/50-udev-default.rules:SUBSYSTEM=="drm", KERNEL!="renderD*", GROUP="video" rules.d/50-udev-default.rules:SUBSYSTEM=="drm", KERNEL=="renderD*", GROUP="render", MODE="0666" rules.d/50-udev-default.rules:SUBSYSTEM=="kfd", GROUP="render", MODE="0666" rules.d/60-drm.rules:ENV{ID_PATH}=="?*", KERNEL=="renderD*", SYMLINK+="dri/by-path/$env{ID_PATH}-render" I believe the creation of this group should be added to the ebuild.
Noticed this too. Related upstream commits: https://github.com/systemd/systemd/commit/f301622d840ae414e7f56c364fe9b035f3041539#diff-a4f86f7bfc24194b276c22e0ef158197 https://github.com/systemd/systemd/commit/4e15a7343cb389e97f3eb4f49699161862d8b8b2#diff-a4f86f7bfc24194b276c22e0ef158197
The systemd-sysusers service has now automtically created the group on my system. This happened after I switched to the new 17.1 profile. So it seems to me that this service (and possibly other important ones?) does not work with the old lib layout.
