Neither you nor I seem to be happy with the fix. When I added this sysctl,
I only wanted to somehow get to the list of changes from UserConfig
without poking around through kmem. Now, when the changes in the way
devices are registered are introduced, we can think of something else
which could be better suited. For now the only programs that need it are
kget and sysinstall. (i.e. it's still easy to change, if we know what we
want.. :-)
