For the first time in a few months I was able to run 'apt-get dist-upgrade' on my Alpha unstable installation. However, be aware that the new udev seems faulty. It continually printed: udevd[448]: unable to receive ctrl connection: Function not implemented in my logs files, completely loaded up the CPU and filled the system disk within 30 minutes. Downgrading udev back to 166-1 worked for me. Cheers Michael.
