The absolute worst mess I've ever seen using NFS was a place where the
previous sysadmin tried to setup Veritas Cluster Server on /opt, where
/opt was NFS shared from one of the cluster nodes and mounted off that
node by the other cluster node.  Not much thought was placed into what
happens if the first box goes away. :-)  But I digress, this place had
every machine's opt mounted from this one.  I suppose that made sense
back in the days of 100MB hard drives, but these were 18GB drives (this
was about 8 years ago.)
