Unfortunately this time it seems to be a lot harder, the main change
being at least to my understanding, the fact that the openafs kernel
module doesn't advertise its services as a system call, and thus we
cannot link with just libc code which calls into the kernel, but need to
explicitly use openafs calls for the same propose resulting in a need to
link to their code.
Hope is not lost totally yet as I've read about some work of developing
a GPL licensed kernel module, and then we could use some glue code from
there.
