Here's an example of how useful this can be. I work in an environment in which the /usr/local directories on our production machines are mounted from a central NFS server. This is great, because if we need to build software for our servers that isn't supplied by the distribution vendor, we can just build it from source in that tree, and all of the servers can access it as soon as it's built. However, occasionally we receive support tickets saying that something is acting strangely or isn't working.
