When a socket is created, you can optionally bind to local IP, interface and/or
IP-Port. Somewhere, NFS is opening a socket I assume? So, is there a way to
ask it to bind?



As David said, the place to fix it is in xs_bindresvport(), but there is
no support for passing this sort of information through the current NFS
binary mount structure. You would have to hack that up yourself.

I can think of some horrible hacks to grab info out of a text file based
on the mount point or some other available info...but if I actually
attempted to do it right..would you consider the patch for kernel
inclusion? Is it OK to modify the binary mount structure?
