Linux-3.6 converts NFSv2/v3/v4 into modules, and so modprobe.conf
entries of the form

alias nfs4 nfs

will now fail to ensure that 'mount -t nfs4 ...' works. In order to
facilitate the task for the distros when dealing with kernels >= 3.5.x,
we've added the automatic module alias so that they can remove the
hard-coded aliases in modprobe.conf while remaining backward-compatible.
