From: J. Bruce Fields <bfields@xxxxxxxxxxxxxx>
The current kernel code should not be enabled by default, because it
does not yet attempt to be a conform completely to the rfc; for example,
some required pieces of protocol are missing.
Therefore the kernel defaults to leaving minorversion1 off. When the
code matures sufficiently, that default will change.
That kernel default becomes meaningless if nfs-utils always explicitly
turns 4.1 on or off. So, nfs-utils should by default do nothing.
Early adopters that want to turn on NFSv4.1 explicitly can still do so
using
echo "+4.1" >/proc/fs/nfsd/versions
