svn commit: r270062 - in head: sbin/umount usr.bin/showmount

New Revision: 270062
URL: http://svnweb.freebsd.org/changeset/base/270062

Log:
  Use mount protocol version 3 by default for showmount and umount.
  mount_nfs effectively uses mount protocol v3 by default already.
  v1 mount protocol is being removed along with nfsv2 by a high profile NFS
  appliance vendor and our legacy v1 mount protocol usage causes rpc errors.
