The point of this is to permit unmodified OpenAFS userspace utilities to use
either the OpenAFS kernel module or the kAFS kernel module.

Whilst I might wish to ultimately replace the OpenAFS userspace utilities with
my own set, that's no small piece of work, and so a handy halfway stage is a
mixed environment as outlined above.

Furthermore, the ability to use the OpenAFS userspace utilities unmodified
with my kernel module, and, indeed vice-versa, makes testing much easier.
