Citing from: http://www.time-travellers.org/shane/papers/NFS_considered_harmful.html
"NFS fails at the goal of allowing a computer to access files over a network as if they were on a local disk. In many ways, NFS comes close to the objective, and in certain circumstances (detailed later), this is acceptable. However, the subtle differences can cause subtle bugs and greater system issues. The widespread misconception about the compatibility and transparency of NFS means that it is often used inappropriately, and often put into production when better, more acceptable solutions exist."
I don't know of a proper solution, other then writing in big letters in the documentation about the circumstances under which you can shoot yourself in the feet.
Where is NFSv4?
