Summary:                    mount does not support option v3 for nfs
Description: 

mount does not support option v3 for nfs

the option v3 has the same meaning of nfsvers=3 which is supported

problem is not only a question of standard compliance (use nfsvers=3
instead v3) but a problem in networking when system/root need to do a, for
example

 remount -o [rw|ro] /nfs

and command fails with error EVEN first mount had nfsvers=3 because kernel
convert nfsvers=3 in v3. I suppose it does the same for 2,3,4.
