--- Comment #9 from Matthias Runge mrunge@matthias-runge.de --- some more comments:
you're dropping something to udev-dir. If that doesn't exist, installation will fail. You need to require udev.
Note: udev has been deprecated, see http://lists.fedoraproject.org/pipermail/devel/2012-June/168227.html
