I think the "sync" option is now the default, but you may want to make
it explicit to avoid server-side warning messages.

The NFS maintainers recommend against the "soft" option since it can
result in invisible data corruption. See section 4.3.1 of the NFS HOW-TO:
* http://nfs.sourceforge.net/nfs-howto/client.html
Since you're using TCP (ergo NFS v3 or higher) for transport, you
probably don't need to specify rsize and wsize; the server will specify
the default block size. I think the default for NFS over TCP is 32K
blocks, but that may have changed of late.
