Yes.  The fstab entry is

node10:/usr/local  /usr/local  nfs  rw,noatime  0  0

where node10 is defined in /etc/hosts.  node10 is up and running
well before any of the systems that have an NFS mounted /usr/local
are booted.

Thanks for the pointer.  Fortunately, the cluster is only rebooted 
every 3 to 6 months when I do a complete upgrade (kernel, world
and ports).  I'll keep this in mind for the next maintenance window.
