Out of curiosity, what's problematic about them, and what are the better alternatives we're moving to?
Because if the server goes away you get stuck unkillable processes.
If you have cyclic NFS dependencies between systems it becomes impossible to cleanly boot the environment.
NFS is great in the steady state, but during failure it tends to trigger bad and unexpected behaviour in everything around it.
