The code is trying to mount a file descriptor, and
the Linux 9P module provides no way to do that.
(In fact, that was the very first thing I asked for, years ago,
when I started trying to use v9fs, and to my knowledge,
it still hasn't happened.  Ron and Eric are focused on
replacing NFS, not building user-level file servers.)

I edited the code to call out to a non-existent mount9p
program before it invokes 9pfuse.  If you put a mount9p
in your path that can be invoked:

	mount9p - /mnt

to mount fd 0 onto /mnt, then the -m options will use
that instead of 9pfuse.  Perhaps one day v9fs will ship
with such a program.
