Actually, now that I look, this does not seem to break on older kernels
as long as you use a syntax like:

    # mount -t nfs server:/export /mnt/point -o vers=4

...if, however you use a syntax like:

    # mount -t nfs4 server:/export /mnt/point

...then it fails without the above file in place. I guess the question
we have to answer is: Do we want to continue to support the "-t nfs4"
mount syntax?
