 while that seems to be not to complicated, I seem to have a problem passing the mount options to the kernel. They come down as mount data version "6". Apparently mount(8) or mount.nfs(8) are doing the parsing and send down the legacy data block. So, what is the minimum version of mount or mount.nfs that pass the options down unaltered?
