Thanks for applying the small patch ! FYI: I've opened a bugzilla about your udev concerns to get some comments from our and the upstream maintainer at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=245717 Kay Sievers from the udev team responded: #> That's nothing new.

From my standpoint, you can close this "bug". Thanks! So, no help from this side....
