Achtung Baby. UDEV is changing.

Seen today when upgrading to UDEV 171:

ATTENTION UDEV:
---------------
Kernel 2.6.32 or newer is now required.
OSS emulation modules are not loaded by default, add to rc.conf if needed.
Arch specific cd symlinks are now no longer created.
cd and net persistent rules will no longer be autogenerated,
see <https://wiki.archlinux.org/index.php/Udev> for details.
Errors are now logged (possibly to the console) by default.

Given that I'm developing a system based on UDEV...
Arch Linux is an amazing distribution to develop with!
