On one hand I completely agree with the "keep it in userspace" assertion. However, to my partial disagreement, I do think there is a role for the kernel/drivers to play in at least announcing that they exist to userspace, etc...
Is this not what the device FS really does, even if it is using the VFS to do it?
In other words, just push all device mgmt whatsoever into userspace is to me broken, and I believe that if the original Unix had such an inerface an idea like DevFS would have popped up a long time ago.
If we can avoid a hoaky HP-UX-ish solution to device creation (which seems to be the userland one), I like it. I don't see that it breaks some functionality, but if it does, you've tested it, and it's fundamentally impossible to do with DevFS, there are even other ways to do DevFS.
Mount it in /devfs and let a devfsd UNDESTRUCTIVELY populate /dev, maybe even selecting only certain classes of devices!
I think we are missing some points here, and getting stuck in our ways. That one was just my opinion.
