In ancient (2.4 and earlier) kernels, the nfs server needed to know
about any client that expected to be able to access files via NFS. This
information would be given to the kernel by "mountd" when the client
mounted the filesystem, or by "exportfs" at system startup. exportfs
would take information about active clients from /var/lib/nfs/rmtab.
information would be given to the kernel by ``mountd`` when the client
mounted the filesystem, or by ``exportfs`` at system startup. exportfs
would take information about active clients from ``/var/lib/nfs/rmtab``.
This approach is quite fragile as it depends on rmtab being correct
which is not always easy, particularly when trying to implement
fail-over. Even when the system is working well, rmtab suffers from
fail-over. Even when the system is working well, ``rmtab`` suffers from
getting lots of old entries that never get removed.
With modern kernels we have the option of having the kernel tell mountd
when it gets a request from an unknown host, and mountd can give
appropriate export information to the kernel. This removes the
dependency on rmtab and means that the kernel only needs to know about
dependency on ``rmtab`` and means that the kernel only needs to know about
currently active clients.
To enable this new functionality, you need to:

mount -t nfsd nfsd /proc/fs/nfsd
