I don't really understand why the /sbin/hotplug callout exists
at all. If instead the kernel were to spit the event strings
out of some FIFO device (character special or whatever) then
hotplugd can perform all its actions nice and serially.
Plus we can buffer all the "insertion events" which occur
from boot-time scanning so they're available when hotplugd
starts up.
Confused.
