Loading modules via loader.conf is many times slower than doing it from
disk after the system is partially booted. (As in, 2-3 seconds per
module vs. nearly instantaneous for all 6.)
I didn't offer my list as an example of what to do, I offered it as a
syntax example. I would of course expect people to use appropriate
discretion to load things in loader.conf that are necessary for boot.
(Of course, the fact that people can easily get this wrong is a strike
against the technique.)
There is no point in having an _enable for this script because if the
kld_list is empty, nothing happens.
Nothin' ever doesn't change, but nothin' changes much.
