Nothing fancy, really. I mounted it manually with:
mount -t 9p -o trans=tcp,aname=/some/path,version=9p2000.L 127.0.0.1
/mount/point. I can take a look at /proc/mounts to tell you all the
mount options, including default ones if you need.

I noticed you sent a patch, I will try that and come back with the result.

Thanks a lot for the support, Dominique!
