#4179: systemd (udev) wants group 'render'

 In version 236 NEWS:

 The "uaccess" udev tag has been dropped from /dev/kvm and
 /dev/dri/renderD*.  These devices now have the 0666 permissions by
 default (but this may be changed at build-time). /dev/dri/renderD*
 will now be owned by the "render" group along with /dev/kfd.

 The group name can be changed by updating the rule in /lib/udev/rules.d/50
 -udev-default.rules or before install, rules/50-udev-default.rules.in.

 SUBSYSTEM=="drm", KERNEL=="renderD*", GROUP="render",

 I do not see a need for a separate group as the default permissions are
 0666.  If the assigned group is not available, then the group remains at
 the default: root.

 Perhaps we should just remove the GROUP="render" assignment.

 Note that /dev/dri/renderD* appears to be used by a video driver.  See
