I presume everyone on this list has been following this discussion on
LKML.  If not, I highly recommend you check out the discussion thread in
the LKML archive.  This is an important architecture discussion that has
very important implications for the Hotplug system.

Here's the first message in the thread:

There are currently ~30 messages in the thread.  I think many of the
most recent messages are probably the most informative and interesting.

Cheers,
