[added hotplug list to the cc]

scsi_id is included with the udev source now, and can be used to solve
most of the problem.

We still need something that tells udev what to do with multiple matches -
for multi-pathed sd's showing up multiple times, we don't want to drop the
other sd's, and that is what will happen right now with udev.
