That is kind of klunky.  How about a utility that snapshots the
permissions and reestablishes them at boot up?  You could try to run it
at a clean shutdown if we ever get beyond a "10 seconds before you're dead"
shutdown.

Site policy doesn't belong in the kernel.  Other policy does, which
is why I think I prefer a devfs versus a symlink approach of establishing
aliases for the "shallow" (/dev/*) device names.  I'm being wimpy
because I haven't thought about this much yet.
