Udev needs to install native systemd service files? It does that when
built with systemd installed, or when configured like that.
  $ ls -l /lib/systemd/system/udev*.service
  Mar 15 18:33 /lib/systemd/system/udev.service
  Mar 15 18:33 /lib/systemd/system/udev-settle.service

Also add:
  systemd.log_level=debug systemd.log_target=kmsg
to the kernel commandline to get all debugging output if needed.
