udev 046 does not properly handle net devices, as I reported earlier on linux-hotplug-devel@sourceforge.net. Kay Sievers quickly provided a fix. For those who cannot wait (not long I bet) for Greg to release a new ebuild (or a new udev) I made an ebuild (udev-046-r1). The patch from Kay must be copied into files directory in your $PORTAGE_OVERLAY.
Created attachment 44287 [details] new ebuild this needs Kay Sievers' patch
Created attachment 44288 [details, diff] patch from Kay Sievers
I'll do a new release with this patch in it later today...
What is the status of this bug? Is the fix in portage yet? If yes, what version of udev has the fix?
Yes, it is fixed in later udev versions.
