async This option allows the NFS server to violate the NFS protocol
and reply to requests before any changes made by that request
have been committed to stable storage (e.g. disc drive). Using this option usually improves performance, but at the cost
that an unclean server restart (i.e. a crash) can cause data to
be lost or corrupted. In releases of nfs�utils upto and including 1.0.0, this option
was the default. In this and future releases, sync is the
default, and async must be explicit requested if needed. To
help make system adminstrators aware of this change, �exportfs�
will issue a warning if neither sync nor async is specified.Should we stick with 'async', or be safe and use 'sync'?

This could have a performance impact. If I remember right, previous implementations assumed async, which tends to give better performance, but is not as conservative.
We should probably choose one and explicitly state it in the config file.
See "man exports" for details.
