Well, I'd like to see a 'generic' unload module instead. In the PCCARD/PCMCIA realm, devices can come and go 'on the fly', so having an unload module and moving towards a more dynamic scheme would be a good thing. For example, in the network devices there is no way of removing an interface from the list although we can add one 'on the fly'. By doing this I think you'd be support a large percentage of the above, and it would also be useful for other parts of the system. However, I think finishing DEVFS would be a better thing to do with your FreeBSD hacking time right now, don't you think? ;) Nate
