Well, that might be a usable model for embedded environments, but since you wouldn't offer PCCARD support, PnP support, or any of the other dynamic technologies which need high-level intelligence support, you wouldn't really be much better off than by using a shell script, so I don't think what you describe will be a much wanted solution... And please, could we try to aim the discussion at how we handle the advanced technologies in or out of devd ? The degraded cases are always easier to handle afterwards.
