I assume then that klibc is out of tree? I can't find it in my
kernel repo.
sorry for late reply, indeed you'll find it here:

we might still define those for ourselve, let's see..
That makes sense to me as an immediate fix.
However, the kernel has its own NFS mount client (the piece that
handles rpcbind query and obtaining the root file handle), and you can
pass a C string of mount options to the kernel with mount(2). Perhaps
in the long term, you might consider replacing the specialized code in
klibc with simply passing the server, export path, and mount options
right to the kernel and let it do the work. This should work with any
kernel later than 2.6.23.
I'm happy to help with any questions.
