<p><b>Warning</b>It is strongly recommended that the print

files should <span class="emphasis"><i class=

or on a file system which is NFS exported.</p>

<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>
