there's nothing specific so much as i just want a clear idea of the
*big* picture.  all of the documentation i read is perfectly adequate
in terms of explaining the low-level details, but is maddeningly vague
in discussing how it all hangs together at the *highest* level.

one thing i'm still unclear on is how, if you can't traverse the sysfs
tree from the top down, how does a power down cleanly start to shut
stuff off from the leaves and work its way back up?  how does the
power down procedure *get* to the leaves of the tree in the first
place?
