Re: setting device permissions for DEVFS

Ah, yes.

BTW: Devices don't disappear if you unload devices.
This happens for example with bktr.ko.
When I then reload bktr.ko, I get the following:

WARNING: Driver mistake: repeat make_dev("bktr0")
WARNING: Driver mistake: repeat make_dev("tuner0")
WARNING: Driver mistake: repeat make_dev("vbi0")

Hmm.  A technical question: How would the devd be notifed about an
event in the devfs?
Does it open a (new) device as for example the usbd does, or how would
you solve that?
