The rule is - if it can be done in userspace, it is. And if it can't be done
in userspace, you implement as little as possible in the kernel, and export
an interface that lets the rest be done in userspace. C-A-D is a good example -
you need to have the basic handler in the kernel, but the actual reaction to
it is in init, and specified by inittab.
So, the stuff that I'm willing to stick in the mconsole driver are things like
diagnosing a sick UML (where you may not be able to start processes - mconsole
proc, which barely passed muster with Al Viro) and pulling hardware in and
out.
