  Hi Jamie,

  Don't do it.
  The point of NFS is to share a part of the filesystem across several
computers. A supervised service is local to a machine; service
directories store local information. Things such as service PID and
lock file cannot be shared. (Even if NFS locking works, you don't want
to prevent a service from starting up on a machine because the same
service is already up on another.)

  Keep local information on local filesystems.
