HP Dynamic Root Disk (DRD) manual Drd sync system shutdown script

5.5 drd sync system shutdown script

To run the following script during system shutdown, create the script in the /sbin/init.d directory and create a symlink to it from /sbin/rc[n].d/K[mmm]. The system administrator can choose values for n and mmm to ensure that file updates made during shutdown occur before the script is run. The script must be run before file systems are unmounted, which is generally done by /sbin/ rc0.d/K900localmount. See rc(1) for further information on rc script numbering.
