This brings me to my (small) beef with devfs.  When you invoke an
abstraction, a metric of the usefulness of that abstraction is how
well the abstractions metaphors map onto the target system's
metaphors.

So as a filesystem, devfs does will by replicating the average
person's view of should be in /dev ... subject to what devices are
actually found... 

But filesystems also have persistence.  In the trivial case, the
persistence of the object (say ... a disk) preserved the filesystems
node.  But if I walk into /dev and change the permissions on a node,
this persists only until the next reboot.

Now... part of the problem here is that there is no simple interface
for the kernel to access (and update) a file ... which might be an
easy way to store persistence... but that's all a larger design
problem.

Now we do have the /etc/devfs.conf ... but this doesn't (yet) approach
the topic of devices added and removed from the system.  Maybe this is
a natural extension for devd.
