site table precreatemypostscripts attribute
'''''''''''''''''''''''''''''''''''''''''''
If the site table precreatemypostscripts attribute is set to 1 or yes, it will instruct xcat at nodeset and updatenode time to query the db once for all of the nodes passed into the command and create the mypostscript file for each node and put them in a directory in $TFTPDIR(for example /tftpboot). The created mypostscript.<nodename>. file in the /tftpboot/mypostscripts directory will not be regenerated unless another nodeset or updatenode command is run to that node. This should be used when the system definition has stabilized. It saves time on the updatenode or reboot by not regenerating the mypostscript file.

If the precreatemyposcripts attribute is yes, and a database change is made or xcat code is upgraded, then you should run a new nodeset or updatenode to regenerate the /tftpboot/mypostscript/mypostscript.<nodename>. file to pick up the latest database setting. The default for precreatemypostscripts is no/0.

The default for precreatemypostscripts is no/0.
When you run nodeset or updatenode, it will search the **/install/postscripts/mypostscript.tmpl** first. If the **/install/postscripts/mypostscript.tmpl** exists, it will use that template to generate the mypostscript for each node. Otherwise, it will use **/opt/xcat/share/xcat/mypostscript/mypostscript.tmpl**.
