:I think the main reason is Matt couldn't find estd so he just hacked u

:would be a better basis for future improvement.
It took less than 2 hours to write it, but also I want to implement
a scheduler integration feature that does not exist in estd at all
that will allow us to consolidate processes on fewer cpus when the
load is low.
I'm just asking because I wrote ACPI support for Dragonfly in estd and I
'm the current maintainer of estd.
If there is a technical reason to have a proprietary implementation I'm
all for it, but the whole power management stuff is quite fragmented alr
eady with lots of
different implementations that do the same thing slightly different.
