Correct, but kqueuing /dev is not nearly as expressiv as devctl,
where the protocol has space where the device driver could pass
useful information to devd(8).
For instance, I find the regexp matching of ethernet drivers very,
very silly: the device driver should just tell devd(8) that it is
an ethernet, so that we don't have this non-documented registry of
device driver names.

Never attribute to malice what can adequately be explained by incompetence.
