[opensuse-packaging] packaging udev rules

Hi, What are the guidelines for packaging udev rules? 1) So far I've found that files should be placed in %{_udevrulesdir}. 2) Should the package call "udevadm control --reload" in %post and %postun? I've found that there's a macro for this %udev_rules_update [1]. But I couldn't find any package doing that.
