A similar message has been shown after quite a few previous udev updates, not just this last one. I remember having to add the CONFIG_DEVTMPFS=y option to my gentoo kernels at least 6 months ago after seeing a message telling me that this option must be enabled for udev or there'll be big problems later on. I have all update messages emailed to me using: PORTAGE_ELOG_*=<blah> In my /etc/portage/make.conf After every update I read every message that portage sends me and I act appropriately upon them. BTW, My udev update went without a hitch. I had a revdep-rebuild to do for a libudev update and that was about it. Even if you didn't see the message and your system didn't boot then you could still fix things by using your Minimal Install CD to start up, then chroot into your normal system and rebuild your kernel. -- Regards, Gregory.
