          <p><b>Warning</b>It is strongly recommended that the
          print spool directories and essential printer
          configuration file files should <span class="emphasis"><i
          class="EMPHASIS">NOT</i></span> be in an NFS mounted file

      <p>The <b class="APPLICATION">LPRng</b> <b class=
      "APPLICATION">lpd</b> print server makes heavy use of file
      locking to coordinate and synchronize process activities.
      Given the historical and ongoing problems of file locking on
      and NFS mounted file system, not to mention the high overhead
      for doing file locking in a distributed environment, it is
      strongly recommended that spool directories <span class=
      "emphasis"><i class="EMPHASIS">NOT</i></span> be on an NFS
      mounted partition or on a partition that is NFS exported.</p>

      <p>This warning extends to other network file systems as
      well.</p>

      <p>In addition, the configuration file such as <tt class=
      "FILENAME">/etc/printcap</tt> must be available or printing
      will not function. Care should be taken to ensure that these
      files are stable and available at all times.</p>
