    I don't see some of those in mount_nfs(8):
    nfsvers=3 -> nfsv3
    noac -> ? (does this option exist on FreeBSD?)
    lock -> lockd (which is the default)
    rsize=65536 -> -r=65536
    wsize=65536 -> -w=65536

    It is possible the documentation is not complete and those options are
    perfectly valid. If so, I apologize.
