The proposal is to modify MI code in kern_subr.c to pass on the howto
variable
which describes whether the shutdown event is a reboot or a shutdown
(or whatever else). This would
allow, say the wd driver to decide whether to spin down the hard disk
before shutting down power
( this was the issue that brought up the discussion in the first place.
)

Yes, but it doesn't sound like its going to happen immediately. What
I'm proposing is an interim solution.
Thanks,
