Asking udev for "the physical device" will not make sense in the new sysfs layout, that just has parent devices and does not distinct between "locigal" and "physical". I didn't know how to implemet %b while replacing libsysfs in udev. Marco had a nice idea and we hopefully found a good compromise to make it working again. udev 081, is expected to fix this. Note: The devfs scheme is completey broken by concept and you should definitely avoid it. The identification numbers of the disks, that the devfs scheme assigns your devices is completely unpredictable in a usual setup and pretty useless cause of this. Switch to the /dev/disk scheme, that was designed to work reliable in a modern environment and which solves all these problems.
